Nitrogen (pre)charged dampener(s) reduces the residual pressure variation to the specified level.

Choice of materials and linings for corrosive and abrasive slurries.

Genuine, contoured and rod- guided diaphragm selected from a range of eight sizes, based on empiric duty related data allows for routine annual replacement.

The poppet valves are the only wear parts. Various valve designs and wear/corrosion resistant materials ensure a most economical mean time between replacements.

Oil-hydraulic valve seat removal. Typical 98% availability, up to 96% efficiency.

Single over-pressure relief valve protects all diaphragm chambers.

Forged alloy-steel crank- Sealed against exterior shaft driven from external contamination. gear reducer. Guided low velocity piston running in clean propelling liquid.

Pre-loaded, long-life roller Conservative rod bearings enable rated load rating. pressure at low speed.

Replaceable Resilient, robust cast cross-head guides frame, shaped for low stress throughout. Integral forced-feed lubrication.

Supervisory control panel PLC for all logic, sequencing and alarm raising functions.

Interactive touch panel for operator convenience. Oil-hydraulic stud tensioning enables rapid valve replacement.

High-pressure diaphragm housing minimizes stress in clamping rim area.

Oil-hydraulic stud tensioning eliminates inaccuracies and stress from torquing. Complete range single and double-acting pumps (shown above), modular design with wide variety of matching units.
