A new and complete range of pumps for transferring and delivering oil, operated by direct current motors. PIUSI products respond perfectly to market demand. The pumps are especially designed for transferring oil from drums, or mobile tanks, in situations where electricity or pneumatic connections are not available. The motor is equipped with a direct current battery so that oil transfer or delivery operations can always be carried out.
Use the pressure-switch version to deliver oil without the inconvenience of having to start or stop the pump.
Thanks to their compactness and easy installation these pumps can be used for equipping mobile oil pumps on vehicles or used independently with battery equipped trolleys. They can also be used as primary installations when carrying out oil transfer or handling operations in yards, ports, aboard vehicles or boats.

Description
«R» series pumps are positive displacement, rotary, internal gear. The capacity is directly proportional to the rotation speed and almost independent of the pressure. The flow is smooth and non-pulsating in either directions. Depending on the application, the pump will be supplied with a packed gland or a mechanical seal mounted single, single with quench, double in tandem, double back-to-back or with a magnetic coupling. The «R» Pumps are manufactured in cast iron or stainless steel. Special materials or material combinations can be used when necessary. The Pumps can be equipped with heating jackets and/or by-pass (relief valve).
Applications
The «R» Pumps are used for liquids of any viscosity as solvents, chocolate or bitumen. The liquid may be lubricating or non-lubricating and may contain abrasive particles as color pigments.
«R» pumps can be used best in one or more of the following circumstances:
- viscous liquids
- constant capacity
- smooth non-pulsating flow
- self-priming
- long life

The pumps are based on the geometry and properties of the cycloid. In fact, they are lobe pumps (or internal gear pumps). All of the main components are made of sintered materials. In the development of these two types of technology, we have given an emphasis to high performance in terms of capacity and pressure in proportion to the pump size (owing to the reduction in unused volume), as well as to duration and lower noise level (owing to the porosity offered by the powder metallurgy).
Self-lubrication is another important property intrinsic to every model of this product, and it is a guarantee against buckling.

Rotor pump is also named rotary lobe epump, three-lobe pump, sole pump,etc. When the 2 simultaneous reverse rotating rotors(with 2-4 gears)revolve, it produces suction force at the inlet(vacuum),which intakes the material delivered.The 2 rotors divide the rotor housing into many smaller parts and revo-Ive in the sequence of a→b→c→d.When it revolves to position a,only housing I is filled with medium;when it revolves to position b,housing B encloses part of the medium,when it goes to position c,housing A encloses medium,and finally it goes to position d,then housing A,B and II are interlinked and the medium is transported to the outlet.As this process is repeated，medium(material)is transpor-ted continuously.
