Introduction to Concentric D Series Hydraulic Pumps

Concentric offers one of the widest selec-tions of gear pumps and hydraulic motors in the industry. All Concentric products are designed to provide solutions to our customers’ application challenges.

Concentric D Series Hydraulic Pumps are compact, external gear models for use in pumping fluids with lubricating quali-ties. Suitable for use in a wide variety of

applications, including agricultural, con-struction, transmission charge and lube, and diesel fuel transfer. Our D pumps are designed to provide reliable, long life service under rugged conditions. D Series pumps are built with cast iron bodies and hardened steel gears.

The Concentric line of D Series pumps covers a displacement range from 0.23

in.3 (3.8 cc) to 1.395 in.3 (22.9 cc). Single, tandem, triple and quadruple configurations are available. The D Series also offers a large selection of shaft and flange options to meet your application requirements.

Installation InformationFLUIDS - Most premium grade petro-leum base fluids can be used with the D Series pump. Optimum operating viscos-ity is 16-63 cSt (80-288 SSU) at maxi-mum rated speed. Minimum operating viscosity is 10 cSt (59 SSU). Maximum operating viscosity is 750 cSt (3409 SSU). Maximum cold start viscosity is 2000 cSt (9091 SSU). Contact Concentric for addi-tional information regarding the D pump performance using other fluids.

OPERATING TEMPERATURES - Fluid temperature range (Mineral Oil):

Max. 93oC (200oF) continuous and Max. 105oC (221oF) intermittent.

FILTRATION - Proper filtration is critical to the trouble free operat-ing of any hydraulic system. For optimum pump life at maximum pressure ISO 4406/1986 (Code 18/14) is recommended. A 10-micron filter sized to accom-modate full system return flow is recommended for most operating environments.
