FAQs
What does the service kit include and what pumps is it compatible with?
This service kit includes replacement diaphragms, valves, and a diaphragm-key tool for proper reinstalling. It is designed for use with the MD1 and MV0.5 diaphragm pump models.
Why should the diaphragms and valves be replaced periodically?
Over time, diaphragms and valves undergo wear — especially with exposure to liquid, dust, or chemical vapors. Worn parts can reduce flow rate, lower vacuum performance, or even cause leaks. Replacing these wear parts restores pump performance and reliability.
How often should I perform maintenance on a diaphragm pump using this kit?
Under normal, non-aggressive service conditions, diaphragms and valves are typically replaced after ~15,000 operating hours. If the pump handles corrosive gases, vapors, or particulates, more frequent inspection and maintenance are advised.
What improvements or issues can I expect after using the service kit?
After replacing the diaphragms and valves with fresh components, the pump should regain original vacuum performance, proper flow rate, and leak-free operation. It also reduces noise and prevents potential failure or loss of vacuum integrity.
Are there special maintenance procedures or precautions when replacing parts?
Yes, always disconnect the pump from power, allow any residual charge to dissipate, then wait until the pump cools before disassembly. Replace one pump head at a time to avoid mixing parts. Wear protective equipment and clean components thoroughly before reassembly.
