6/4D-AH(R) Slurry Pumps for frac sand processing

6/4D-AH(R) Pumps for frac sand processing

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.

Throat bush – 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.
