Delta P D Pumps Private Limited manufactures Shuttle Block Pumps. Delta P D Pumps Private Limited offers different types of pumps. The Shuttle Block Pumps are a combination of Rotary and Piston pump- two double acting pistons in their respective cylinders at right angles to each other. Rotation of rotor causes reciprocating movement of shuttle and piston. The self priming single shaft design with long sleeve-bearing supports the external ball bearing. Single gland construction reduces leakage to minimum. The front pull out design permits inspection of parts without disturbing the pipe connection, couplings or prime mover. Slow speed operation contributes to high reliability and less maintenance. Product is pumped without shear, foaming, agitating, heating, emulsifying or chewing. Pumping elements are of simple geometric form. Parts can be manufactured locally in any part of the world by a small repair shop.
