Viking's spur gear pumps perfect for viscous oil

Kelair's client required pumps to incorporate two portable oil filter carts which were to be used in a mobile application.

The oil is new but has to be filtered for use in engines on large mining machinery. The oil is quite viscous at 460cSt and the pumps had to deliver the oil at 8bar discharge pressure to meet the requirements of the filter.

Because the carts are portable the overall physical size of the pumps would be important and motors would be 240v/50Hz single phase.

The pumps were required to deliver 32 L/min and 69L/min.

For 32 L/min we selected a Viking SG-0716 spur gear pump with Viton lip seals and iron bushes. A 2.2kW 6 - pole (950 rpm) 240v/50Hz motor was sourced.

To meet space requirements a bell housing was used to couple the pump to the motor rather than a traditional baseplate and guard.

For the 69 L/min application we selected a Viking SG-0722 spur gear pump set up in a similar manner to the first pump but with a 4-pole (1450rpm) motor to meet the duty requirement.

As lead time was critical the pumps were placed on the Viking quick shipment programme to ensure they were delivered on time.
