P700 Hydra-Cell Pro Metering Pump

Seal-Less Metering Pump — 139 to 1,394 GPH, up to 1,200 PSI

The Wanner Hydra-Cell^® Pro P700 metering pump provides API 675 compliant performance for steady-state accuracy, linearity and repeatability at flow rates as high as 1,394 GPH and pressures to 1,200 PSI.

Its seal-less design enables reliable metering of a broad range of difficult fluids at high pressure without the risk of fugitive emissions or leakage. Unlike piston and plunger pumps that rely on packing and seals that wear and leak over time, the P700 has no dynamic seals and reliably handles non-lubricating, abrasive and extreme-temperature fluids.

Technical Specifications

Flow Control

Maximum flow rate is determined by the gearbox ratio used to limit pump shaft speed, with an optional variable-frequency drive for additional turndown. The P700 is a standard Hydra-Cell Pro Model D35 pump fitted with a gearbox that mechanically reduces shaft speed for lower flow rates while minimizing motor and VFD horsepower.

Most VFDs offer programmability and can interface with a customer-supplied PLC.

User-Friendly Design & Low Maintenance

The only components in contact with the pumped fluid are the elastomers and check valves (5 diaphragms and 10 check valves). Diaphragms have no defined wear life — testing for approximately 20,000 hours of continuous operation showed no appreciable wear. Check valves typically last 6,570–8,760 hours (9–12 months of continuous operation), depending on fluid characteristics and the materials selected.

Check valves are easily replaced without special tools or training. In many cases the change-out can be completed without removing the pump from the process line and within about 90 minutes.

Complete pump/motor/VFD/PLC assemblies are available. Provide your design criteria and we will size the motor and optional controllers accordingly.
