Product Description

GPY-F Series Gear Pump Overview

The GPY-F Series Gear Pump is a miniature high-pressure hydraulic gear pump developed for precision and high-pressure hydraulic system scenarios. Adopting high-precision integral gear design and optimized internal sealing structure, this pump features compact size, ultra-light weight, high pressure resistance and stable output performance. The whole pump body is made of high-strength die-cast aluminum alloy, which has excellent rigidity, corrosion resistance and heat dissipation performance, effectively avoiding deformation and oil leakage during long-term high-pressure operation.
Different from ordinary gear pumps, the GPY-F series has extremely low pressure fluctuation and stable flow output, adapting to high-frequency continuous working conditions. With fine machining process and strict assembly standards, it achieves low noise and high volumetric efficiency during operation. The product supports diverse installation methods and interface specifications, with strong versatility. It is a high-cost-performance miniature hydraulic power unit widely used in precision industrial equipment and small engineering machinery.

Factory&FAQ

Q1: What is the main advantage of GPY-F gear pump compared with ordinary gear pumps?

A1: This series adopts floating side plate compensation structure, with higher volumetric efficiency, lower noise and smaller pressure loss. It can work stably under high pressure for a long time, with lower failure rate and longer service life than ordinary gear pumps.

Q2: Can you provide customized services?

A2: Yes. We support custom rotation direction, shaft size, mounting flange, oil port thread and special specification parameters. OEM logo and packaging customization are also available.

Q3: What is the product warranty period?

A3: We provide 12 months factory warranty for all GPY-F series pumps. During the warranty period, non-human damaged products can enjoy free repair and replacement services.

Q4: How about your delivery time?

A4: Conventional standard models are in stock and can be delivered within 3-5 working days. For bulk orders or customized products, the delivery cycle is 7-15 working days according to the order quantity.

Q5: What kind of hydraulic oil is suitable for this pump?

A5: It is recommended to use anti-wear hydraulic oil with viscosity of 10~200 mm²/s. Clean hydraulic oil can effectively extend the service life of the pump. It is forbidden to use inferior and impurity-containing hydraulic oil.

Q6: Do you provide after-sales technical support?

A6: Yes. We have a professional technical team to provide 24-hour online technical guidance, including equipment installation, debugging, fault diagnosis and daily maintenance guidance.
