850 Series Horizontal Filtrate Pump

Rugged in design and dependable in nature, the 850 is a proven performer in some of the earth’s toughest environments. 

Capable of operating in vacuum conditions up to 26″ Hg, the 850 is well suited for vacuum filtration and dewatering systems with difficult suction conditions. 

A vent port allows pumping to resume even after short periods of interrupted flow, assuring continuous pumping, from a trickle to full capacity.

With a semi-open impeller and a variety of material choices ranging from duplex stainless steel to rubber lined, the 850 is ideal for abrasives and light slurry duty in the mining, power generation, and pulp and paper industries.

The 850 is available as either a close-coupled or frame-mounted unit with an option for a side-mounted motor with belt drive. 

By using either a belt drive or a variable frequency drive (VFD), performance can be fine-tuned to match most system requirements. The front and back pull-out design allows for easy maintenance. 

The pump comes standard with a packed stuffing box and flush water connections to ensure lubrication and eliminate vacuum or air leakage. 

A variety of shaft sealing options is available to meet the requirements of specific applications.
