Products

Group 1 product is defined by the mounting flange and shaft end. Mounting flanges can be the SAE “ AA” two bolt, the US 4F-17 four bolt, four bolt European mounting flanges, and the “through-bolt” front manifold discharge DC power-pack deisgn pump. Shaft ends can be keyed, spline, or tang depending on the customer requirement, Displacements offered are from .04 to .82 cubic inch per revolution depending on the specific model. Side ports are generally standard but rear ports can be available depending on the specific model.
Group 2 product is defined by the mounting flange and shaft end, and the function, be it pump or motor or bi-directional pump. Mounting flanges can be SAE “A” two bolt and four bolt European mounting flanges. Shaft ends can be keyed or spline or tapered depending on the customer requirement, Displacements offered are from .24 to 2.02 cubic inch per revolution depending on the specific model. O-ring side portsare standard but rear ports can be available depending on the specific model.
Group 3 product is defined by the mounting flange and shaft end, and the function, Mounting flanges can be SAE “B” & SAE ”A” two bolt and four bolt European mounting flanges. Shaft ends can be keyed or splineor tapered depending on the customer requirement. Displacements offered are from 1.1 to 5.5 cubic inch per revolution depending on the specific model. O-ring side ports are standard but rear ports can be available depending on the specific model.
INSTALLATION NOTES
Verify rotation required as the wrong rotation can rupture the shaft seal. Check for proper shaft alignment as axial or radial loads are not permitted. Chain and belt drive is not recommended.
 
HYDRAULIC FLUIDS
The fluid must be specifically for hydraulic systems. A mineral oil based hydraulic fluid is recommended. For best service it should have anti-wear, anti-foaming, anti-oxidant, and anti-corrosion properties. Fluids should comply with DIN 51525 and VDMA 24317. Allowable temperature range of the oil is -10C to +80C. Fluid kinematic viscosity ranges are the following: Permitted range: 6-500cSt. Recommended range: 10-100cSt. Maximum start up value: <2000cSt.
 
Filtration
System filtration of 25 micron absolute (B=75 to higher) or better is required. Finer filtration is recommended. Pump wear due to oil contamination will not be cause for warranty consideration. New installations should require the system oil be filled through a 10-micron absolute filling system. Water contamination of the oil is not allowed.

A typical model code would include the following:
 
SERIES 
is pump body size, group 1 or group 2 or group 3. 
TYPE 
refers to the type of pump, or motor it can be as further defined by the flange and gear set.
FLANGE 
is which front cover/flange depending on the gear set/shaft diameter.

SHAFT 
is defined based on which flange is required and refers to the diameter and the end style, e.g.,

keyed, tang, spline, tapered. 

PORTS 
are specific based on which series and flange is required. The size of the ports is generally defined by the pump series and displacement. Ports are SAE o-ring standard, and flange side ports standard, with rear port cover option.

DISPLACEMENT
is based on series and type.

ROTATION
is “R”for clockwise (cw) and “L” for counterclockwise (ccw) as facing the shaft end. On bi-rotational motors and pumps, the rotation code is not required.
