Spare Part Kits

Quattroflow® pumps are primarily maintenance-free thanks to their robust construction. However, the diaphragms, valves and O-rings should be checked regularly and, if needed, should be replaced using the Spare Parts Kit: "Diaphragms-Valves-O-Rings." We recommend a maintenance interval of 1,000 hours of operation or at least once a year. Depending on the operation conditions (pressure, temperature, flow rate, SIP, etc.), it may be necessary to significantly shorten the maintenance interval for the elastomers. 

The following parts are included in the Spare Parts Kit: “Diaphragms-Valves-O-Rings” (the quantity depends on the pump size):

  • Diaphragms
  • Inlet valves
  • Outlet valves
  • O-ring kit


For corrosion reasons or a clearly audible operating noise, the parts in the Spare Parts Kit: “Shaft-Bearing-Cap-Unit” should also be replaced. The kit consists of the following parts:

  • Eccentric shaft
  • Bearings
  • Bearing holder
  • Bearing cap
