Garbarino P Self Priming Positive Displacement Pump

The Garbarino P Pump has been designed for use on wide ranging applications within the marine, chemical, petrochemical, paper, food and paint industries. The Garbarino P can pump different fluids from viscous and lubricating to aqueous ones and therefore seizing liquids, slightly and medium abrasive products, aggressive fluids, etc..

The Garbarino P Pump is self priming by construction, even with empty suction pipes and no suction valves. The priming capacity is related to the suction pipe layout and pumped liquid.

Garbarino P Pumps are bi-rotational, which means that they maintain their characteristics when they pump in both directions simply by reversing the direction of motor rotation.

The P Pump has a maximum number of revolutions of 480RPM. This means that the shaft, the bearings and the rotor with its elastic device rotate at a maximum of 480 RPM. A low number of revolutions guarantees a long life while maintaining its characteristics. As there are very few moving parts, the reliability of the P Pump and its installations are guaranteed. Low speed is obtained by means of a reducer between motor and pump.



The pumping oscillating hollow disk is kept in contact with the pump body by an elastic device (spring + cap). This device allows the passage of considerable sized solid particles in suspension, as these particles remain in the available space and therefore do not seriously damage the body and the rotor. It also allows the recovery of play due to wear, at the same time maintaining the characteristics of capacity and head of the pump even with viscous, abrasive or chemical fluids.
The hollow disk is pivoted eccentrically with regard to the pump shaft and is driven by a baffle-plate separating the suction orefice from the delivery one. The shaft rotation drags the hollow disk in an oscillating movement and keeps it always tangent to the outer and the inner cylindrical surfaces, thanks to two diametrically opposed generating lines, thus forming two movable hydraulic seals.
