POLARIS 10 SERIES
Hydraulic Gear Pumps and Motors

PRESSURE
Max. continuous 3770 psi (260 bar)
Replaces edition: 10.1995

Max. intermittent 4060 psi (280 bar)

Max. peak 4350 psi (300 bar)

DISPLACEMENT SPEED

To 0.60 in /rev (9,9 cm /rev) Max. speed 4000 rpm

POLARIS 10 gear pumps and motors meet a wide range of mobile and industrial applications. SAE and EUROPEAN
mounting flanges and rear covers are available in both cast iron and aluminum for reduced weight. The extruded aluminum
body houses single piece gear, journal, shaft assemblies with a pressure balancing system that provides the highest
volumetric and overall efficiencies available. Exceptionally large bearings make possible longer life at high pressure. A
complete range of drive shafts in spline, parallel keyed, and tapered versions to meet all SAE, and EUROPEAN standards.

(1) Minimum speeds can be reduced, maximum speeds can be increased. For specific operating conditions consult CASAPPA tech-
nical dept. for recommendations and approval.
(2) Significantly higher intermittent pressures are allowed. Consult catalog or contact CASAPPA technical dept.
(3) Flow shown is minimum allowed for production pump at rated pressure with 10 wt oil at 110° Fahrenheit and can be used to cal-
culate minimum volumetric efficiency under these conditions.
(4) Indicated torque is obtained by considering the average mechanical efficiency.
(5) Weight shown is for pump and motor with cast iron end-covers. There is a weight reduction for aluminum covers.
(6) Available only for single units with shaft code 81.
(7) Available only for single units with shafts code 81 and 86.
Please contact your CASAPPA distributor for further assistance.

POLARIS 20 SERIES
Hydraulic Gear Pumps and Motors

PRESSURE
Max. continuous 4060 psi (280 bar)
Replaces edition: 02.2996

Max. intermittent 4350 psi (300 bar)

Max. peak 4640 psi (320 bar)

DISPLACEMENT SPEED

To 1.99 in /rev (32,6 cm /rev) Max. speed 4000 rpm

POLARIS 20 gear pumps and motors meet a wide range of mobile and industrial applications. SAE and EUROPEAN
mounting flanges and rear covers are available in both cast iron and aluminum for reduced weight. The extruded aluminum
body houses single piece gear, journal, shaft assemblies with a pressure balancing system that provides the highest
volumetric and overall efficiencies available. Exceptionally large bearings make possible the most complete range of drive
shafts in spline, parallel keyed, and tapered versions to meet all SAE, DIN, and EUROPEAN standards.

(1) Minimum speeds can be reduced, maximum speeds can be increased. For specific operating conditions consult CASAPPA tech-
nical dept. for recommendations and approval.
(2) Significantly higher intermittent pressures are allowed. Consult catalog or contact CASAPPA technical dept.
(3) Flow shown is minimum allowed for production pump at rated pressure with 10 wt oil at 110° Fahrenheit and can be used to cal-
culate minimum volumetric efficiency under these conditions.
(4) Indicated torque is obtained by considering the average mechanical efficiency.
(5) Weight shown is for standard pump and motor with cast iron end-covers. There is a weight reduction for aluminum covers.
Please contact your CASAPPA distributor for further assistance.

(1) Minimum speeds can be reduced, maximum speeds can be increased. For specific operating conditions consult CASAPPA tech-
nical dept. for recommendations and approval.
(2) Significantly higher intermittent pressures are allowed. Consult catalog or contact CASAPPA technical dept.
(3) Flow shown is minimum allowed for production pump at rated pressure with 10 wt oil at 110° Fahrenheit and can be used to cal-
culate minimum volumetric efficiency under these conditions.
(4) Indicated torque is obtained by considering the average mechanical efficiency.
Please contact your CASAPPA distributor for further assistance.
