Pressure Compensated Piston Pump 167-0994 For 950 Series Wheel Loaders

Hydraulic Piston Pump Introduction

The 167-0994 hydraulic piston pump is a slipper-type axial variable displacement piston pump, primarily used to convert mechanical energy into hydraulic energy. It provides high-pressure fluid output through the reciprocating motion of the piston, with a displacement of up to 74 L/min, and features high efficiency and reliability. This pump is widely used in the hydraulic systems of heavy-duty construction machinery such as the 950G, 962G, and IT62G series wheel loaders, as well as some backhoe loaders, meeting high pressure and high flow requirements and exhibiting stable and reliable performance under harsh operating conditions.

This series of variable displacement piston pump features exceptionally fast response times and solid dynamic behavior. Built with a rugged housing and reinforced bearing system, it supports prolonged service intervals even when subjected to frequent pressure cycling and heavy loading. Widely appreciated in mobile and stationary systems needing quick adaptation to changing operational demands.

Hydraulic Piston Pump Usage Precautions

• Cleanliness First: The most common hydraulic system failure stems from oil contamination. Thoroughly clean lines, tanks, and filters before installation, and avoid mixing different brands of oil. Regularly sample and check oil contamination levels, maintaining NAS 1638 level 8 or higher.
• Daily Inspection and Maintenance: Check the pump for operating noise, vibration, and leaks daily; periodically visually inspect or check bearing clearance (average life approximately 10,000 hours; replace immediately if scratches or discoloration appear). Monitor system pressure and temperature, avoiding exceeding pump ratings (typically several hundred bar). Keep variable displacement mechanisms clean and prevent jamming.
• Safe Operation: High-pressure systems pose risks; release pressure and wear protective equipment during operation or maintenance. Do not touch high-temperature components or perform maintenance while the pump is running.
