High compression ratio for a steader flow and better efficiency
In Ragazzini pumps the piston stroke is longer than the diameter of the cylinder; this results in a high compression ratio and therefore an higher flow rate with a smaller number of revolutions. It is a pump with slower movements but a longer piston stroke. The whole mechanical part is thus improved, but in particular you obtain a more constant and compact flow, a greater self-priming capacity.
More efficient compensation to avoid any vibration and wear in the pipes
In Ragazzini pumps the dampeners have the shape and size that is most suitable for an uniform distribution of the high working pressure. They are placed directly on top of the suction and delivery pipes. In Ragazzini pumps the phenomenon generated by alternated pressures is already limited, but such an high compensation, so close to the pipes where the pressure is discharged, totally is eliminated.
More linear thrust to avoid mechanical wear and energy losses
The “sector” movement driven by a double support, common to all Ragazzini models, allows for the perfect alignment of the piston, thus providing the linear thrust necessary for the correct functioning of the piston gaskets and of the seals with Teflon gland rings.

General descriptino
HINDHIVAC manufactures different models of Rotary Piston Vacuum Pumps. These Rotary Piston Vacuum Pumps are robust and are most reliable. They can be used in combination with Roots Vacuum Blowers.
These Piston Pumps are extremely useful in handling high volumes of gases and are provided with Gas Ballast Valves to pump out condensable vapors. These piston pumps are built to give uninterrupted service even under strenuous working conditions with economical power and oil consumption.
These Piston Pumps are water cooled to ensure continuous duty with high efficiency. The Piston Pump has a unique design in which the pump ensures that while the piston continues to rotate it maintains isolation of the compression and the suction cycle, drawing out the compressed air through the exhaust valve. The pump has a low oil charge and the gas ballast is provided to avoid oil contamination due to condensable vapors. This Piston Pump is water cooled to avoid over heating and for continuous running
