Edelmann & Associates, Inc.

Distributor of Industrial Positive Displacement Pumps from Viking Pump, Wilden, Liquiflo, Wright Flow Technologies & Seepex.

Viking Pump is recognized as the world leader in gear pump technology and their pumps are designed with an operating capacity up to 1,600 gpm at -120°F to 800°F, with fluid viscosities of 0.5 to 1,000,000 cSt (28 to 4,500,000 SSU). Viking Pump has over 100 years of experience on some of the toughest applications in the Industrial process markets, and they offer several configurations and metallurgies to provide solutions for some of the toughest liquids to handle.

Our line of Wilden air diaphragm pumps offer special features and configurations, making them an ideal choice for a wide range of applications. They are built with anti-freezing air valve technology in bolted or clamp band construction, are portable, can handle large solids, and come in a wide range of sizes configurations and capacities.  They are also easy to maintain and can handle flow rates up to 350 gpm. 

Wright Flow Technologies circumferential piston and rotary lobe pumps offer no metal to metal contact in the pumping chamber in a twin wing rotor and optional single wing rotor design for large solids handling. These pumps are ideal for food processing or for when gentle handling of product or solids is required. They feature a variety of port options with capacities up 836 gpm and pressures up to 500 psi.

For more than 30 years, Seepex has been offering Progressive Cavity Pumps to customers in the chemical, food, paper, petroleum and gas industries for delivering low to highly-viscous, aggressive and abrasive media.

We offer all of these quality products to customers across Minnesota, Western Wisconsin, North Dakota, and South Dakota. View Details of our Positive Displacement Pump Manufacturers Offerings.
