H25 Series (US) / G25 Series (Metric)

Diaphragm Pump Features

Versatile, Reliable Pumps for a Wide Range of Applications

  • Pumps the full spectrum of low-to-high viscosity fluids.
  • Features a seal-less design and horizontal disk check valves that enable the pump to handle abrasives and particulates that might damage or destroy other types of pumps.
  • Simple, compact design reduces initial investment and lowers maintenance costs.
  • Operational efficiencies reduce energy costs.
  • Able to run dry without damage (or additional maintenance) to the pump in case
  • of accident or operator error.
  • Tolerates non-ideal operating conditions.
  • Minimizes maintenance and downtime because there are no seals, packing or cups to leak or replace.

Valve Selection

Choose the valve for this Diaphragm Pump

C63 Pressure Regulating Valve

A seal-less C63 Pressure Regulating Valve is recommended for Hydra- Cell H25 pumping systems, especially for high- pressure requirements or when handling dirty fluids.

C23 Pressure Regulating Valve

A C23 Pressure Regulating Valve provides a capable, lower-cost alternative to C63 valves for Hydra-Cell H25 pumping systems.

Minimizes maintenance and downtime because there are no seals, packing or cups to leak or replace. Operational efficiencies reduce energy costs.

Hydra-Cell Heavy Duty Pumps have proven their performance and reliability in the toughest industrial equipment and process applications.

When we say “Simply Built to Last”, we mean it!
