Stable Low-Voltage Output Auxiliary Pilot Pump HPV091 For EX200-2 Excavator

Pilot Pump Introduction

The HPV091 pilot pump is a small gear-type auxiliary pump, typically installed on the HPV091 series main hydraulic pump (axial variable displacement piston pump). Its primary function is to generate stable, low-pressure pilot oil to drive the spool valve of the main control valve, ensuring sensitive response of the excavator's operating handles and precise control of the hydraulic system. This pump features a compact design, high efficiency, and strong wear resistance, making it suitable for long-term reliable operation under heavy loads and harsh conditions.

This pilot pump series serves as the reliable foundation for hydraulic control systems in modern machinery. It generates stable, low-pressure signals that translate operator inputs into smooth and accurate machine movements. The entire range is developed with a strong emphasis on consistency, making it easy for equipment manufacturers to standardize components across different machine models.
