Diaphragm Pump FAQ

  • My pump does not turn on.
    1. Check for power (Supply voltage +/- 10%)
    2. Check pressure switch. Please see ESR-008.
    3. Check relay – It will make a click sound if failed. (FB2/FB3 series demand pump)
    4. Replace motor
  • My pump is not flowing.
    1. Check valve. Please see ESR-002.
    2. Check for inlet leak like a broken hose, fitting or loose hose clamp preventing the pump from priming. May need a new pump head. Please see ESR-003.
    3. If the pump is still not flowing, replace the lower housing and/or valve plate. Please see ESR-003.
  • My pump is not shutting off or does not build pressure.
    1. Check for correct voltage (Supply voltage +/- 10%)
    2. Check for system debris, leaks, trapped air.
    3. Check for low flow. Replace the Lower Housing Assembly. Please see ESR-003.
    4. Check for pump head leaks (tighten screws or new pump head)
    5. Adjust pressure switch. Please see ESR-001.
  • My pump is turning on and off quickly (Cycling).

    Pump ‘cycling’ is when the pressure switch of any demand style pump is rapidly turning on and off. Understanding why your pump is doing this is essential to finding a solution to the issue.

    • Understanding Pressure Switches

    To understand why your pump is cycling it is important to understand how a pressure switch works.  On the top of all demand style pumps there is a pressure switch. Inside the pressure switch is a small diaphragm connected to an electrical On/Off switch. Once the pressure in the pump head reaches a certain pre-set limit (ex. 60 psi) the diaphragm will inflate and hit the electrical On/Off switch turning your pump off. Once the pressure in the pump goes below the pre-set limit (ex. 60 psi) the diaphragm will deflate turning the pump back on.

    • Flow vs. Restriction

    The flow of your Delavan Pump and your system’s restrictions are the next factors to consider. The flow of your Delavan Pump is written on the label of your pump. For this example, you have a 5 GPM Delavan pump and have it hooked up to nozzles or a spray wand. The nozzle or wand is only able to put 2 GPM, this is the restriction of your system. Your pump always wants to push 5 GPM but the system restriction won’t allow it. This causes your pump’s pressure switch to rapidly turn On/Off. Much like any electrical system, turning your pump On/Off rapidly is causing damage and may cause your pump to prematurely break down.

    • How do I stop my pump from cycling?

    Recognize what is causing the restriction. It could be the size of your nozzles, the wand you are using, a kinked hose in your system, the diameter of the hose, too many 90º fittings. It can be one or a few of these issues. Fixing the restriction and increasing the flow of your system will stop cycling.

    If you are using a Sprayer or Wand type system you can easily add a return to tank or “bypass” which will circulate any extra fluid back to the tank. Do this by adding a T-fitting and valve just past the outlet and a hose which will direct any excess flow back to the tank.  We have a Youtube video explaining this; https://www.youtube.com/watch?v=QEN6AXZrAGM

    Finally, you can adjust the pressure of where your pressure switch will turn off power to your pump by adjusting the set-screw on top. Follow this link for an explanation of how to do that. Please see ESR-001.

  • My pump leaks.
    1. Check for loose screws at switch or pump head.
    2. Check the switch diaphragm ruptured or pinched. Replace the pressure switch. Please see ESR-008.
    3. Check for fluid in the pump head. If present, replace the lower housing assembly. Please see ESR-003.
    4. If you have a 7822FS serial number and the pump is leaking from the Flex-Ports please see Please see ESR-027.

  • Why does my pump get very hot?

    Delavan pumps are equipped with high torque continuous duty cycle motors. They are designed to run continuously at pressures less than 50-60 PSI.
    If the motor is getting hot, typically the pressure is high causing the motor to work harder.

    Solutions:
    1. Reduce the operating pressure to 30-40 PSI

    2. If pressures higher than 50-60 PSI are required, introduce a duty cycle, use the pump for 50 minutes and then let it rest for 10 minutes to allow the motor to cool down.

  • Import vs Domestic Pump

    Any pump with an ‘-I’ at the end of the model number is an import pump. The upper housing assembly and valve plater are not replaceable with a standard domestic pump. Pressure switches are interchangeable on all models and so are lower housing assemblies.

  • Demand vs Bypass

    A demand pump shuts off at pressure setting. You can identify a demand pump by the wire leads out of the pump head (pressure switch). A bypass pump runs continuously when it has power. You can identify a bypass pump since they only have 2 wires out of the motor.

  • Are Delavan diaphraphm pumps self priming? Can they run dry?

    Diaphragm pumps self prime and can run dry.

  • Which models are potable water safe (NSF)?

    All models are NSF certified except import and FB3 (7871/7971) series pumps.

  • Fuse/Wire Size
  • Chemical Compatibility

    Please contact Delavan Techincal Support to discuss your application.

  • Can I adjust my pressure switch?

    Adjusting the pressure switch may increase pump wear and tear which therefore reduces pump life.

  • What does Extreme Duty mean?

    Extreme Duty pumps are made with stronger and heavier duty Geolast diaphragms. Pumps with Geolast diaphragm exhibits enhanced oil-resistance and low oil swell making it ideal for oil based applications. Geolast provides moderate flex life and good abrasion resistance over a wide temperature. Should not be used with gasoline.

  • Can I pump diesel through my pump?

    Never pump gasoline, flammable liquids or combustible liquids. Pumps with santoprene diaphragms are designed for use with water-based products only. Pumps with Extreme Diaphragm (ED) designation are made with Geolast Diaphragms and are compatible with non-flammable and non-combustible oil-based liquids.

  • Can I pump bleach through my pump?

    Yes, you can pump bleach through any Delavan PowerFLO Pump.

    Sodium hypochlorite or bleach is a key component in thousands of production and disinfection processes in a variety of industries. Though testing we have found that sodium hypochlorite does affect the elastomers (or elasticity) of the pumps diaphragm over time. Simply put, a pumps diaphragm is similar to an elastic band and continuous use over time with bleach will cause it to dry out and have less elasticity.

    There are steps you can take to prolong the life of a diaphragm pump used in conjunction with bleach.
    1. Flush out you pump after each use with fresh water for 90 Seconds
    2. Dilute the bleach. Delavan recommends a concentration of 12%. (Similar to the concentration used in most soft wash applications)
    3. Replace the pump’s diaphragm every 12-18 months (depending on usage) or when you begin to see a significant drop in flow.

  • What size pump should I use for my application?

    In order to optimize the performance and life of your Delavan Fluid Power pump we recommend matching your systems output GPM as close as possible to the pumps GPM. For example if you have a four nozzle boom and each nozzle puts out 0.5GPM at 40PSI, you would want a pump close to 2.0GPM.

    If you are replacing a pump on a sprayer system try to match as close as possible the GPM of the pump you are replacing. Moving to a larger pump with a higher GPM output will cause the pump to cycle therefore reducing the life of the diaphragm and pressure switch.

    For help on deciding which pump is best for you, please call 1-866-DELAVAN and one of our representatives will be happy to help you.

Hydraulic Cylinder FAQ

  • Will the stroke controls damage my shaft?

    No. The segments are made from aluminum which is softer then the chrome coating on your shaft and do not cause damage.

  • How do I install the stroke controls?

    The stroke control segments or “pucks” clamp on to the cylinders shaft

  • What is a stroke control used for on a cylinder?

    A stroke control segment is used to control the return stroke of a hydraulic cylinder.

  • Can I use my Delavan cylinder in single acting mode?

    Yes. A breather plug is required which keeps contaminants and moisture out of the cylinder end opposite the oil. Please see ESR-021 for installation instructions.

  • What does ASAE mean?

    ASAE stands for American Society of Agricultural Engineers. ASAE was developed in order to create standards for products in the agricultural market. By adhering to these standards, consumers can ensure they will get the same specifications of a product, no matter where they purchase it from.

    ASAE is applied only to hydraulic cylinders with the 8″ and 16″ stroke.

    Cylinders labeled 8″ ASAE will have a retracted length of 20.25″ (Pin to Pin)

    16″ ASAE will have a retracted length of 31.5″ (Pin to Pin)

  • What does single acting mean for a hydraulic cylinder?

    Oil flows to move the piston/rod in one direction and load/gravity returns the cylinder back to its original state.

  • Why is my Delavan PowerMax Cylinder leaking?

    Dampness on the piston rod is a sign of a possible cylinder leak. Hydraulic Fluid leaks are caused by worn seals of the cylinder rod gland. (Debris getting past the filters, side load, shock loads, etc.) The good news is hydraulic cylinders are some of the simplest hydraulic components, making them easy to repair. In fact, you can do some of these repairs by yourself.

    It is recommended you investigate the cause of the seal leak to prevent your cylinder from leaking and needing repairs again.

    Delavan Fluid Power now offers seal repair kits for all Tie-Rod PMH and PML Hydraulic Cylinders. To find and purchase the correct seal for your cylinder please call 1-866-DELAVAN.

    When you call please be sure you have;
    1) Cylinder Part Number (ie. PML4024-150)
    2) Cylinder Serial number which is etched into base of cylinder.
    Our customer service team will be happy to help you find the seal kit right for your cylinder.

Hydraulic Valve FAQ

Roller Pump FAQ

  • How do you prime a roller pump?

    Delavan Fluid Power requires all roller pumps be gravity fed during priming. Roller pumps need liquid in the pump while priming or the heat due to friction can cause rollers and seals to melt. Never run a roller pump dry.

  • Can all Roller pumps be directly connect to a PTO?

    No. The 4 Roller is the only pump that can not be directly connected to a tractor PTO shaft. If you wish to use it on a PTO, a gearbox is required to increase the speed to 1800-2600RPM.

  • Does the needle bearing need to be greased?

    No, it is sealed and ready to run.

  • Can a roller pump be run dry?

    No, it will melt the pump parts.

  • Can I use Round-up with a cast iron pump?

    It is not recommended to use Round-up with a cast iron pump. A stainless steel pump is better suited for this application.

  • Can Delavan pumps be used with Ethanol?

    No, our pumps cannot be used with Ethanol. The internals will swell and lock up.

  • Are rollers installed a specific way?

    No difference even if the ends are not the same.

  • What is the best way to store my RollerPRO pump in the off-season?
    1. Flush out your roller pump with clean water well enough to get rid of the chemicals used. (if need be, take off the cover in order to expose the rollers and flush out that way as well for a more complete clean)
    2. Use a light oil on the inside of the pump to coat the parts, if you can, rotate the pump for complete coverage
    3. For best storage, place in a temperature controlled environment.

    Please refer to ESR-013.

  • My Roller Pump does not have the same pressure it used to have. Why?

    Over time, small particles can enter the pump and cause damage by wearing the rollers. Once this occurs the pump will lose the solid seal between each roller preventing effective pumping.

  • My pump is rusty. How should I clean it?

    You can clean the pump with steel wool. Please refer to ESR-013.

  • What should I check if my pump does not flow?
    1. First, try priming the pump by pouring water into the inlet of the pump.
    2. Check the rollers for damage. If they are damaged, purchase a repair kit. See Roller Pump Repair Kit list.
  • What should I check if my pump does not turn?
    1. Check internals for rust and oil.
    2. If it still does not turn, purchase new bearings and repair kit. See Roller Pump Repair Kit list.
  • Why did the Shaft break on my Roller Pump?

    There are a few reasons that the shaft can break on Delavan Roller Pumps. The number one reason we see is misalignment of the Pump Shaft to the PTO causing stress on the Shaft. This is similar to having a side load on the shaft. We have a repair kit for each size pump which contain a replacement Shaft, Rotor, Pill Key, Shaft Seal and Ball Bearing which could be used to fix it.

    Please see below for the correct repair kits and part numbers;

    4900 Series Pumps: RK-31410-RT
    6900 Series Pumps: RK-31610-RT
    7900 Series Pumps: RK-31710-RT
    8900 Series Pumps: RK-31810-RT

    Also if the pump was run dry the added heat could cause the pump shaft to get hot and weaken. If that were the case you may need to also purchase the RK ROLLER PUMP REPAIR KIT SERIES which contains a Shaft Seal , Roller Bearing,End Plate Seal and 4, 6,7 or 8 Rollers. It is easy to see if the pump was run dry if you take the end plate off by taking out the four bolts in the corners and seeing if there are any melted rollers or seals.
