1- Leakage, contamination, and unusual outgassing are the general causes of problems associated with poor vacuum. To operate at maximum efficiency, a system must be thoroughly clean. If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked. A simple criterion for the condition of the pump is the determination of its maximum vacuum capability. This can be accomplished by blocking of the intake and reading the vacuum level on the gauge. If you pump does not have a built in gauge, a low cost relative dial gauge can be found here.
Contact Us for assistance connecting gauge to evaluate pump.
2- Worn mechanisms. Piston pumps, regardless of brand, all contain wear items. If your pump can no longer achieve sufficient vacuum after thousands of running hours, piston cup, valve and seal replacement is necessary. Please Contact Us with make and model of your pump for the correct service kit. Piston pump repair does not require advanced mechanical skill and is usually performed in-house.
3- Damaged Valves. Replace flapper valves.
4- Debris in valves. Clean debris and check for valve damage.
5- Damaged gasket. Replace gasket
6- Loose fitting. Tighten fitting.Contact Us for correct maintenance parts, tools and detailed instructions for do it yourself in-house repair assistance.
