Progressive Cavity Pump
Progressive Cavity Pump
(OP)
Hi folks,
I have to install a Progressive Capacity Pump and I wish to do the motor run test. Now, the problem is that the pump data sheet mentions "Coupling- No, Block-Yes". I believe, this 'block' does the function of the coupling. Does anyone know if I can remove the block (easy or difficult?) and test the motor before commissioning it?
Thanks in advance...

RE: Progressive Cavity Pump
SHUTTLE BLOCK Pumps employs a unique pumping principle - a combination of Rotary and Piston Pump. Two double acting pistons in their respective cylinders at right angles to each other, accomplish this, while the rotor turns without the need for any valving. The shuttle block pump is a self-priming Rotary Pump.
There are only three pumping elements - ROTOR, PISTON and SHUTTLE. Rotor is keyed to a single shaft and runs concentric in pump casing. It has a rectangular slot across its face. The channel shaped piston reciprocates within this slot. A rectangular blocks, shuttle, fits liquid tight in piston slot and reciprocates. The reciprocating action of piston in rotor and shuttle in piston is due to and eccentric pin fixed on the pump cover and engaging the shuttle bore as the rotor turns in the pump casing.
Like a true piston pump, this pump can handle highly viscous liquids or thin volatile material with unmatched suction characteristics and yet smoothly without pulsation this pumping principle unlike centrifugal or gear pumps gently handles the product without breaking it down, emulsifying, foaming, chewing or heating: an added advantage at no extra cost.

1) Fertilizer 4) Petroleum Refineries
2) Food Processing 5) Soap & Detergent
3) Paint & Resin 6) Railway & Ports
