Linden Industries Inc., which makes polyurethane processing equipment in Cuyahoga Falls, Ohio, has expanded its Rexroth polyurethane pump repair services to include other pump brands: the RHL model from Rotary Power Pumps, Viking and MHR.
Linden also increased its range of pumps that provide magnetic coupling conversion, to include RHL and Rexroth pumps, low-pressure gear and feed pumps and day tank agitators.
Officials said Linden has seen a surge in demand for magnetic coupling conversions. The traditional seals used in pumps and agitators can deteriorate, leading to leakage of polyol and isocyanate, the company said. By converting to magnetic couplings, the inner magnet is isolated within the pump case.
To make the conversion, the pump drive shaft seal is replaced with two magnetic assemblies. The magnets create force that transfers torque from the motor to the driveshaft.
