Polaris Pumps – State of the Art Submersible Slurry Pumps
Designed to handle the toughest services in a broad spectrum of solids handling and slurry transport applications, Polaris pumps feature a wide selection of wet end configuration options and run dry capable, severe duty submersible motor combinations that enable us to configure a submersible pump solution to meet your specific requirements.
The Polaris pump line-up utilizes a modular wet-end platform approach with common wet end components for a given pump size. The final configuration to a plain open suction, mixer or shredder type pump is accomplished by adding kit components that are interchangeable and can be added or changed in the field as necessary.
Primarily designed for heavy duty slurry applications, the wet-end components including the strainer are made from abrasion resistant High-Chrome white iron for maximum wear life. CD4MCu duplex stainless steel wet end components are also available for corrosive applications. This enables us to meet the requirements of almost any application ranging from effluent water and waste water disposal, FGD sumps and abrasive slurry transport to food processing waste, wood yard waste and recycling.
Regardless of what your application may require, we can configure a cost effective and efficient solution for your pumping needs.
One of the largest U.S. dairy farm operations in the Pacific North West contacted our local representative to help them resolve ongoing pump maintenance problems and pump failures at their dairy’s methane digester installation. The farm’s innovative methane digester reduces greenhouse gas emissions by converting dairy waste into fuel. Collecting the methane gas from the manure and using the fuel at the dairy is a key goal of the farm’s sustainable farming practices. The manure collected from the dairy’s flushing systems is stored in agitated in-ground holding tanks. The original installation employed above ground, self-priming horizontal 
end suction process pumps that transferred the manure to the digesters. Due to the very high suction lift conditions coupled with a high temperature fluid, the transfer pumps were subject to constant cavitation and all of the associated problems such as limited parts wear life, excessive downtime, vibration and noise. The inability of the horizontal pumps to pick up the solids from the bottom of the tank also meant that the holding tanks required periodic cleaning with vacuum trucks every 30 days. After evaluation of all available options an 8” Series TBM 200LH-PBO submersible pump was selected to be installed in the tank. The pump was started and gradually lowered into the slurry and accumulated solids until it came to rest at the bottom of the now cleaned out holding tank. The original horizontal pumps had an average run time of 2 weeks or less whereas the TBM 200LH submersible has now been operating continuously for the last 14 weeks of the initial 100 day trial period without any diminished performance or downtime. This is just one of many examples where the joint efforts between Polaris Pumps, our professional field representatives and the end user produce innovative solutions and solve pump maintenance and process problems.
