Unit eliminates maintenance cost

Problem

The Orihula Sanitary System in Fremont, Wis., had 150 progressing cavity pumps on a 3-inch pressure main serving a subdivision designed for 30 homes, but with only eight built. When two converted to seasonal use, the flow was not enough to scour solids from the line, which clogged. Orihula’s contractor, Fremont Plumbing & Heating, flushed the pipe and replaced stators on the pumps often, at high cost.

Solution

An engineer from Jim Murray Inc., a Crane Pumps & Systems distributor, analyzed the main, then modeled it using Barnes replacement core units with Barnes Omni Grind Plus centrifugal pumps. The computer model indicated that replacing seven existing pumps with the core units would eliminate clogging and repairs. The universal design of the units fit directly into the wet wells. Other features include greater velocity to eliminate odor and clogging, and the grease-proof, environmentally sealed pressure switch level control for trouble-free operation.

Result

Phil Hering of Fremont Plumbing & Heating reports the system has not needed flushing since the new units were installed. 937/615-3544; www.cranepumps.com.
