BJM Shredder Pump

Like other machines, pumps are subject to improvement and evolution. Today, the pedestal style sewage pumps that were mainstays in commercial and industrial wet pit sewage ejector systems throughout the 1960’s and ‘70’s are being phased out in favor of a new generation of light-weight, submersible, energy-efficient units that are cheaper and easier to install and service.

 

Traditional pedestal or "column" pumps sit atop discharge piping that can measure several feet in length and weigh several hundred pounds. These pipes are generally made of steel and are therefore prone to corrosion. The pumps themselves were designed before consumer plastics came into heavy use and are subject to frequent clogging.

Repairing a pedestal pump usually requires it to be lifted from a wet pit, which can take a pair of technicians the better part of a day. Our service division recently pulled a pair of badly corroded pedestal pumps from the basement of a six floor office building.

Weighing nearly 300 pounds each, the pumps had to be lifted out of the wet pits they had been installed in 20 years before with a gantry crane and chain blocks. A initial inspection showed extensive decay around the discharge piping.

Pump Products' service division, Pump Express, replaced the old pedestal pumps with a pair of BJM 3-horsepower, 3-phase, 230-volt submersible sewer ejector pumps. Along with non-corrosive stainless steel casings, these pumps are equipped with a cutting impeller designed to shear through plastics and other tough solids.

The pumps were wired to a control panel and three-float system. In the event of too much flow entering the pit, the floats will sound an alarm and automatically activate the second pump.

In addition to eliminating the chronic clogging issues that were hampering the old pedestal pump system, the new BJM shredder pump system will cut the time and labor required for servicing in half.
