Wanner Engineering has introduced its new Hydra-Cell Q330 Series pump that features a seal-less design.
The Minneapolis-based firm in the US said this avoided maintenance problems of mechanical or dynamic seals and packing that could lead to leaks and wear.
The pumps have been designed for a variety of high-capacity applications including salt water disposal (SWD), salt water 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.
The company stated the models were available to meet API 674 performance standards.
The new Q330 medium pressure models offer flow rates up to 153 gpm (579 l/min; 5247 BPD) and a maximum pressure rating of 3500 psi (241 bar).
New high pressure models offer flow rates up to 118 gpm (446 l/min; 4047 BPD) and a maximum pressure rating of 4500 psi (310 bar).
The seal-less design means that Hydra-Cell Q330 pumps do not have a leak path and so eliminate hazardous VOC emissions and the clean-up and disposal costs of packed-pump leakage.
This also eliminated the need for external lubrication and maintenance as well as plunger wear problems associated with packing, the company added.
Hydra-Cell Q330 Series pumps can run dry without damage, will operate with a closed or blocked suction line, and can pump hot abrasive fluids effectively.
The patented, seal-less Hydra-Cell Q330 Series 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.
