Single Seal Bolier Feed Pump Manufacturer – GLFW Sanitary Centrifugal Pump – State Machinery Equipment Manufacturing

Application

GLFW series sanitary centrifugal pumps can be widely used in the transportation of various liquid materials, such as dairy products, beer, beverages, medicine, biological engineering, fine chemicals and other fields. It can not only transport ordinary low and medium viscosity solutions, but also transport solutions containing suspended solids or corrosive. Sanitary centrifugal pumps are in the form of single-stage, single-suction, open impellers. The pump casing and impeller are carefully designed to reduce the resistance and completely eliminate the dead angle of hygiene. Due to its special structure, the flow rate of the liquid in the pump is increased, thereby improving the overall performance of the pump, and it is easy to clean and has excellent hygienic performance. It can meet product requirements for hygienic, flexible handling and chemical resistance.

Standard design

GLFW pump consists of the following parts: standard motor, impeller, pump housing, sanitary mechanical seal. It features an in-place cleaning system (CIP) design ,Cleanable seal without dead space inside. The GLFW pump has a stainless steel housing to protect the motor and four adjustable stainless steel legs.

shaft seal

GLFW pumps are fitted with a balanced single mechanical seal or a flushable balanced single mechanical seal. The static ring of these two mechanical seals is made of AISI316L steel embedded with silicon carbide or graphite, and the moving ring is made of silicon carbide. The support seal of the flushable mechanical seal is a durable lip seal. The mechanical seal of the GLFW10B GLFW25B pump is a double mechanical seal.
