Concentric AB-GC PMP-USA-2011-6 4 PORT LOCATION OPTIONS Standard porting is SAE Straight Thread O’Ring Ports. Depending on gear size, porting size varies as shown in the chart below. NPTF and Inlet Tube Ports are not standard, but can be supplied. The second chart shows the Order Code for port type and location. VALVE OPTIONS A variety of integral valves and valve combinations are available as standard. Options include: Relief, Check, and Check/Relief combination. A Check, Relief & Solenoid Release valve combination provides the lift-hold-lower function for power up and gravity down applications. Another unique option, for lift-holdlower applictions, incorporates an adjustable needle valve in the pump for controlling the lowering speed of the load. SEAL & BEARING OPTIONS Five basic seal & bearing configurations are available as shown here. Oil seals are either Buna-N or Viton. Outboard ball bearings are available for “radial load” (bolt or gear drives and thrust loads). High-pressure seals are rated up to 25 PSI at 3000 RPM. Viton seals are rated at 350°F (176°C). Consult factory for other types of sealing materials and mechanical seals. Higher pressure seals available, consult factory. OPTIONS * NOTE: Based on CCW rotation.
