Lowara FH Series centrifugal pumps, which includes the FHE and FHS versions, are manufactured in compliance with EN 733 – DIN 24255 BS standards. They consist of a cast iron pump body and an AISI 316L stainless steel impeller welded by laser technology. Bronze impellers are available on request. These will normally fit models that come with a cast iron impeller. There are three different types of motor-pump coupling available:
• The FHE models that are close coupled by means of an adaptor bracket and with an impeller that is keyed directly into the motor shaft extension
• The FHS models that have a bracket, adaptor and rigid coupling that is keyed into the standard motor shaft extension
• The FHF models that have a racket, support, flexible coupling and an aligning and anchoring base
• There is also a bare shaft pump and a version with spacer coupling that is available on request
