6x4E-AHR Industry Centrifugal Slurry Pump with Expeller Seal

Product Brands: Tobee

Tobee® AHR rubber lined slurry pumps are similar to AH metal lined slurry pump in structure. The main difference between AH and AHR is the material of wetted parts, which are natural rubber, synthetic rubber or other wear-resistant rubbers. AHR rubber lined slurry pumps are more suitable in delivering strong corrosive or abrasive slurries of small particle size without sharp edges.

Tobee^® 6/4E-AHR Rubber Lined Slurry Pump is cantilevered, horizontal, centrifugal with double casing slurry pump. They are designed for the handling of highly abrasive, high-density slurries. The wet parts of 6x4 slurry pumps are made of natural rubber, which could be replaceable wear-resistant parts. The discharge side can be oriented to any of the eight different positions. The shaft seals may adopt packing gland seal, expeller seal and mechanical seal.

Design Features:

√ Bearing assembly – A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.

√ Liners – Easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of maintenance. Hard metal liners are completely interchangeable with pressure molded rubber. Elastomer seal rings back all liner joints.

√ Casing – Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.

√ Impeller – Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded rubber impellers are completely interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.

√ Throatbush – Wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.

√ One-piece frame – A very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.

Tobee^® AHR Rubber Slurry Pumps Shaft Seal Arrangement :

• Packing Seal is a general shaft seal.It applys to various pumping conditions, PTFE and Graphite materials of Packing can be used in high corrosive slurries or high temperature conditions.Using ceramic shaft sleeve,For high abrasion conditions, The ceramic shaft sleeve is available.
