High‑speed pumps and compressors

High-Pressure Reciprocating Diaphragm Pump — FPDD

The special structure of the high-pressure hydraulic diaphragm reciprocating pump belongs to static sealing, which can achieve absolute no leakage. The power end is maintenance-free for life (including plunger, stuffing box, seal box, crankshaft connecting rod, etc.), with extremely low shutdown maintenance rate, and the uninterrupted continuous operation time can reach 25,000 hours.

Diaphragm pumps are suitable for discharge pressuresup to 350 bar (5075 pounds per square inch) and liquid tempera-tures  between -40 °C and 150°C (minus 40 ° F to 302  F). PTFEmembranes are suitable for almost all liquids and effectively sealareas in contact with pumped liquids. 

In addition, other structuralmaterials,  suction and discharge valve types, and storage rates will be selected to meet technological requirements.
