lntroduction

Series 11, 14 Description

General

The Denison Hydraulics Goldcup 11 and Goldcup 14 axial piston pumps feature advance design concepts which are time proven and provide for advance pumping and control concepts. The instructions contained in this manual cover complete disassemЫy and reassemЫy of the unit. Before proceeding with the disassemЫy or reassemЫy of any unit, this manual should Ье studied in order to become familiar with proper order and parts nomenclature.

The use of а rocker cam to control the pump displacement provides а small package size, reduces wear, and speeds control response. The control vane actuator eliminates link­ age and backlash inherent in typical stroking cylinder designs.

Standard controls for the Goldcup units are Rotary Servo and Compensator Over-Ride. Additional optional controls are also availaЫe.
