Sealless pumps eliminate emissions, trim maintenance

Wanner Engineering

The Hydra-Cell T200 Series medium-pressure pumps (photo) feature a sealless design that avoids the maintenance problems of mechanical or dynamic seals and packing that can wear and leak. With flowrates of up to 95 gal/min and a maximum pressure rating to 3,500 psi, the Hydra-Cell T200 models are ideal for high-capacity applications including saltwater injection, bulk transfer and hydraulic lift in oilfields and steam generation, reverse osmosis, boiler feed and high-pressure feed. The patented design employs hydraulically balanced, multiple diaphragms that enable the pump to handle high pressures with low stress, and abrasive particulate matter up to 800 microns in size. The sealless design eliminates the potential leak path, thereby eliminating the chance of hazardous emissions, and helping to reduce maintenance and cleanup costs associated with packed-pump leakage. This also eliminates the need for external lubrication and maintenance, as well as plunger wear problems. — Wanner Engineering, Minneapolis, Minn.
