Seal-less pumps have no seals or packing to leak, wear or replace

Wanner Engineering has announced Hydra-Cell Q330 series pumps that feature a seal-less design to avoid the maintenance problems of mechanical or dynamic seals and packing that can leak and wear.

Units are designed for a variety of high-capacity applications including saltwater disposal (SWD), saltwater injection, bulk transfer and hydraulic lift in oil fields, as well as steam generation, reverse osmosis in water and wastewater treatment, mine dewatering, boiler feed, and high-pressure cleaning.

Models are available to meet API 674 performance standards, the company states. Medium pressure models offer flow rates up to 153 gpm and a maximum pressure rating of 3500 psi.

High pressure models offer flow rates up to 118 gpm and a maximum pressure rating of 4500 psi. The series can run dry without damage, will operate with a closed or blocked suction line, and can pump hot abrasive fluids effectively.

The patented pumps employ hydraulically balanced, multiple diaphragms that enable the pump to handle high pressures with low stress and process abrasive particulates up to 800 microns in size, according to the company.

Wanner Engineering is represented in Canada by John Brooks Company.
