Salient Features
Large contact areas between rotor elements result in low unit pressures and less wear and tear unlike in gear pumps. The elements are in hydrodynamic balance.

Micrometer axial shaft positioning device permits controlled clearance between rotor face and cover and even after long use, wear can be compensated by simple adjustment at site to restore pumping capacity.
Piston type pumping action with only four overlapping strokes per revolution contributes to excellent suction. Very high viscosity fluids including pasty and lumpy substances can be pumped with ease.
Pump elements can be inspected and serviced at installation by Front Pull Out" design without the need to disconnect pipes, coupling or motor or any other parts by simply unscrewing the cover bolts.
Shuttle block pumping principle gently moves the product without shear, foaming, agitating, heating, emulsifying or chewing a positive advantage over conventional gear rotary pumps.
Single shaft design with one long sleeve-bearing support and external ball bearing ensures vibration-free smooth running and also permits the use of belt/chain drives. Bearing does not get contaminated with pumping fluid.
Slow speed operations contribute to high reliability and excellent service life without the need for maintenance.
Volumetric efficiency is very high, contributing to low power requirements due to true piston action.
Working Principles
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.
