Hydraulic Gear Pump – 11 GPM, 2-Stage (Brand New)

Description

Product Overview

The Hydraulic Gear Pump 11 GPM 2-Stage HLGP-8.8/3.6 is engineered to deliver precise, high‑pressure fluid movement in demanding industrial environments. Constructed from high‑grade cast iron and hardened steel gears, the pump resists wear, corrosion, and thermal stress, ensuring a long service life even under continuous operation. Its two‑stage design separates low‑pressure and high‑pressure stages, allowing smoother pressure buildup, reduced pulsation, and improved efficiency compared with single‑stage alternatives. The pump’s compact footprint fits easily into tight machine bays, while the standardized mounting flange simplifies integration with existing hydraulic systems. With a rated flow of 11 gallons per minute, the unit meets the power requirements of a wide variety of equipment, from material handling machinery to heavy‑duty presses. The product includes a detailed installation guide, torque specifications, and recommended lubrication schedules to help technicians achieve optimal performance from day one.

Usage

Designed for versatility, this gear pump excels in applications such as CNC machine tool coolant circulation, injection molding hydraulic circuits, and agricultural equipment where reliable pressure delivery is critical. It operates efficiently across a temperature range of -20°C to 120°C, making it suitable for both indoor factory floors and outdoor construction sites. The pump’s low noise level and minimal vibration contribute to a safer workplace, reducing the need for additional dampening accessories. Users can pair the pump with standard hydraulic fluid grades, and its self‑priming capability eliminates the need for external priming devices, saving time during system start‑up. Maintenance intervals are extended thanks to the pump’s sealed bearing design, which protects internal components from contaminants. Whether the system demands rapid cycling, steady‑state operation, or occasional overload handling, the pump’s robust torque transmission and balanced gear geometry provide consistent output.

FAQ

What type of hydraulic fluid is recommended for this pump?

We recommend using ISO VG 32 to ISO VG 46 hydraulic fluid that meets the relevant industry standards. The fluid should be clean, free of contaminants, and maintained at the proper temperature to ensure optimal pump performance and longevity.

Can this pump be used in a mobile equipment application?

Yes, the pump’s robust construction and vibration‑resistant design make it suitable for mobile equipment such as construction machinery and agricultural tractors, provided that the mounting is secured and the fluid is properly filtered.

What is the recommended maintenance interval?

Under normal operating conditions, we advise inspecting the pump and changing the hydraulic fluid every 2,000 operating hours. For harsher environments, more frequent checks may be necessary to monitor wear and maintain peak efficiency.

Is it possible to obtain a custom shaft size?

Absolutely. We offer custom shaft dimensions and optional coatings on request. Contact our engineering team with your specifications, and we will provide a quotation and lead time for the customized unit.

How does the two‑stage mechanism improve performance?

The first stage builds low pressure gradually, reducing shock loads, while the second stage boosts the pressure to the required level. This staged approach minimizes pulsation, improves flow stability, and reduces energy consumption compared with single‑stage pumps.
