How do I change a diaphragm and how long should my pushrods be?
Due to the mechanical setup, specific lengths are not the best way to adjust the pushrods to the correct length. Instead, we use a “clearance” or “gap” adjustment.
- The diaphragm should be installed BOWL-SHAPE IN and cross tightened to a torque of 40 ft/lb.
- When the eccentric lobe is at “Bottom Dead Center,” or the “Six o’clock position,” there should be a 1/8“ to a 1/16” of a gap between the plate and the diaphragm.
This method is similar to how one would adjust the tappet clearance on a rocker arm to a valve in an engine.
How many hours should I be getting out of my diaphragms?
While results can vary, we have a training outline that implements all the best practices to perform when operating a double diaphragm pump in order to get the most out of the diaphragms.
MSP Best Practices for Pump Maintenance
- Be sure the pump is completely flushed out, and there is no debris inside the pump.
- Always use at least a 20ft section of flexible hard hose (suction hose) on the first leg of the discharge. The more hard-pipe the better. DO NOT use the layflat hose directly off the discharge port.
- Only use the primary discharge (key switch) side.
- Position the pump at the highest elevation possible to use the working principles of the pump to PULL vs push the water. Avoid stepping the pump down.
- Use the vacuum relief valve to introduce air to the pumping system. More vacuum does not mean more flow. If you can achieve lift with a lower vacuum, you will get the same pumping result and more hours out of the diaphragms.
- Monitor the diaphragms, and ensure there is not folding, bulging or ballooning. The diaphragms need to cycle smoothly and correctly.
- Diaphragms WILL TEAR at some point. It is important to track the hours for common uses and predict a failure so there are not repeated visits to the pump and avoidable and costly downtime.
- If you are going to service the pump, track the hours on the diaphragms. If they are close to their threshold, it would be a good idea to preemptively change them.
- (Need intro language for this) 2inHG suction with a 50ft discharge vs 20inHg of suction with 400ft of discharge uphill. More pressure and suction means more wear and fewer hours of efficiency.
- To optimize the wear on your pump, be sure to use MSP’s diaphragm coating and protectant to repel harmful UV degradation and “hard” fluid corrosion.

How do I know if my pump is working properly?
Use a vacuum plate to ensure you can reach at least 25inHg. Turn the pump off (while holding vacuum relief closed) to identify any leaks. If the vacuum drops for more than 5inHg in 30 seconds, there is a leak somewhere. Please call us at (904) 524-1320 for immediate assistance.
Why won’t my pump stay running?
Troubleshooting single cylinder diesel engines includes identifying if the issue is fuel, electrical, air or mechanically related.
- Each category has a different set of components that can be easily checked by process of elimination—and we will assist you to trace the main issue.
- Please call 904.524.1320 for immediate assistance.
Why does my pump not achieve any vacuum?
The pump can achieve up to 27inHg of vacuum. We use a benchmark of 25inHg as a testing point while the pump is not in use and at the shop, after is has been completely flushed. VACUUM RECHARGE is a process that is essential to the operation of the pump.
When should I replace my flapper valves?
If your vacuum test indicates leaks, inspect each flapper starting from the lower one and work your way up. Feel around the flapper for any degradation. Replace rubber with the “meat-side” down.
Be sure to monitor hardware as well, and replace when needed. The torque specifications of the flapper mounting bolts is barely 2 to 3 ft/lbs—it’s just enough to allow the lock washer to engage.
How often do I need to change the gearbox oil?
Our recommendation is 5,000 hours first service, then change every 10,000 hours of runtime.
How often do we need to grease the bearings on the diaphragm?
Daily. It is very important to be sure the grease is actually entering the ports and to test for “play.”
What is the torque spec on belt tensioner?
The specification is 30 to 40 ft/lbs.
