P315 Tandem Pump with Integral Port End Priority Valve

By incorporating the priority flow valve and relief valve in the port end housing, this design puts the added flow of a tandem to good use without requiring excessive mounting space for a bolt-on valve. The integral priority flow valve provides primary and secondary flow ports. Flow in excess of that required by the priority circuit may be routed to a power beyond function. These units may be used to provide power steering or braking requirements.

Load-sense Unloaders

These valves may be bolted to any standard pump outlet or used in-line between the pump and a load-sense control valve. Two sizes handle flows from 0-30 gpm
and 30- 60 gpm at pressures to 3500 psi. The unloader effectively modulates pump output relative to function pressure and flow requirements.

Charge/Lube Pump

The design of this unit takes advantage of relatively low pressure operating requirements
(450 psi.) to reduce the number of cast iron components required for its two pump sections from five pieces to three. Relief valves for both sections are built into the pump body. The common journal carrier, one-piece steel drive shaft, and powdered metal driven gears
contribute to the overall compactness of the design while providing charge and transmission lubrication flows.

Through Shaft Pump

An innovative design, this piggyback unit is driven by a common shaft that is actually the drive shaft of the machine to which it supplies two separate flows. The through shaft eliminates the need for a PTO, reduces the number of component parts and contributes to a lighter more compact machine design.

Pump with Shaft End Cover Ports

The unusual shape of this pump’s shaft end housing allows it to fit tight mounting spaces while
maintaining smooth hydraulic line connections. The housing features integral port lobes that allow straight hydraulic line connections without line kinks or space robbing line loops. Overall length of the pump is reduced by eliminating typical gear housing ports.

Add-A-Pump

This special port end housing for P350 and P365 pumps allows a separate pump to be mounted to the rear of the unit as needed for optional machine functions or to provide flow from a separate reservoir. With bearing, lip seal and drain already in place, this special can accommodate any add-on pump with SAE A or B two-bolt mounting pattern and splined drive shaft.

PL Factor
Each section of a multiple pump or motor should be
regarded as a single unit with corresponding delivery
and power input requirements. Since the entire input
horsepower is fed through a common drive shaft, the
power delivered to or from the unit is limited by the
physical strength of the shaft. This limit is defined as
a “PL” factor; “P” being the operating pressure and “L”
the summation of gear widths. In multiple units the “PL” must be calculated for the first connecting shaft as well as the drive shaft. Each style or type of shaft has a unique “PL” factor as noted in the table.

Pressure X Total Gear Width = PL

PL MUST NOT EXCEED NUMBER SHOWN IN
CHART FOR APPROPRIATE SHAFT.
