The PMPO has two model of pumps. The pressure pumps, with a displacement from 0.3 to 2 cc, have a designed pressure of until 120 bar. They also have a standard rotation speed of until 3000 rpm, including a small size or external diameter of 6 cm. The flow-rate pumps, on the other hand, with a displacement from 2.7 to 8 cc, have a pressure of until 20 bar. These have a standard rotation speed of 7000 rpm, including a small size or external diameter of 6 cm.
The given models can be modified by inverting its rotation direction. Moreover, these pumps are self-lubricating and have a long service life.
