Pumps are the heart of any hydraulic system.It’s very likely for the people in the working field to associate the failure of the hydraulic system with the pumps So whenever anything goes wrong, it’s usually the pump that gets the blame. In fact, it’s unusual for a pump failure to be caused by a defe

The Critical of the Components in the Vane Pumps .The following components are critical in maintaining optimum performance of Keisters’ vane pumps The challenge each represents to the remanufacturer is detailed in the following pages. A: Flex Plates (VQ) The depth of metering and timing notches and

1.Preferred ViscosityNormal pump operation (at rated conditions) is based on the use of SAE 10W oil in the 38_ to 82_ C (100_ to 180_ F) range (or comparable viscosities). 2.Permissible Viscosity When operating with SAE 10W oil in the 860 to 40 cSt (4000 to 180 SUS) range (-12_ to 35_ C or 10_ to 95

Pump Start-up Procedure Preparation Prior to Start-up The reservoir and circuit should be clean and free of dirt and debris prior to filling with fluid. Circuit Cleanup The reservoir should be charged with filtered hydraulic fluid. The fluid level should be sufficient to prevent vortexing at the suc

1.Mounting Dimensions Requirements Dimensional control requirements of the customer’s mounting pad to which the pump or motor is affixed are as follows. Pilot Diameter Concentricity of the customer’s female pilot diameter relative to the effective axis of the female drive must be within 0,10 mm (.00

Performance and application of HYDRAULIC VANE PUMPA HYDRAULIC VANE PUMP is the heart of a hydraulic system that converts mechanical power into fluid power driven by a motor. Here is the content list:l The Principle of Operation of HYDRAULIC VANE PUMP l The main points of using a HYDRAULIC VANE PUMP.
