Description

The Warman® SLR pump is a proven horizontal end suction centrifugal pump that will reliably and economically handle abrasive and corrosive medium duty services. Several unique features have been designed into this range of pumps – front and back liners are adjustable to maintain efficiency and wear clearances while the Hi-Seal expeller allows for dry gland operation.

Key features/benefits

Wear is reduced and maintenance simplified by the use of a one-piece volute liner with no radial split at the cutwater
Front and back liners are adjustable while the pump is running to maintain efficiency and minimize wear; also reduces expeller clearance maintaining shaft seal performance
Internal liners can be fully worn as the cast iron split outer casing provides structural integrity and high operating pressure capability
Safe closed valve operation is assured by the pressure relief device fitted as standard on all models
An easily removable hardened steel or ceramic coated steel shaft sleeve with o-ring seals at both ends protects the shaft from abrasive or corrosive contaminants
Reduced and simplified inventory is assured with a minimum number of wearing parts
Reduced seal pressure and internal recirculation is achieved by the pressure molded deep sealing vanes on the front and back of the impellers
Extended bearing life is assisted by large diameter flingers and static seals to prevent ingress of liquids while operating and while stopped
Grease relief holes prevent bearing overheating due to over greasing
The best material for each application can be chosen from the wide range of erosion and corrosion resistant materials, enabling wear life optimization of each component
