HIGH/LOW, 2 STAGE / GEAR PUMPS

Product catalog summary
Overview: The document provides comprehensive information on high/low double stage gear pumps, specifically the 1HL, 1PHL, and 2HL series. These pumps are designed for applications requiring fast actuator movement at low loads and slow movement at high loads, offering advantages such as reduced motor power requirements.
Specifications: The pumps feature a first stage with low displacement and high pressure, and a second stage with high displacement and low pressure. Unloading valve settings range from 30 to 50 bar, and the pumps operate within 1000 to 3500 RPM. They have common inlet and outlet ports with specific side port codes for different series.
Technical Features: The pumps use a Teflon shaft seal capable of withstanding over-pressures of over 210 bar, ensuring a perfect seal and reducing noise levels by an average of 15 dBA. The helical gear profile minimizes pressure oscillations and vibrations, enhancing performance and reducing internal leakage.
Applications: Suitable for log splitters, crimping machines, clamp mechanisms, metal forming machines, and waste compactors, these pumps are beneficial in systems requiring efficient power usage and noise reduction.
Design and Manufacturing: jbj Techniques Limited offers tailored solutions with quick delivery, providing composite bellhousings and flexible drive couplings for different motor interfaces. The company is ISO certified and offers products meeting ATEX certification requirements.
1PHL Series: Designed for waste compactors, log splitters, and metal forming machines, featuring a double-stage pump with integrated valves. The standard pressure setting is 30 bar, with an RPM range from 1000 to 3500.
2HL Series: Used in crimping machines and clamp mechanisms, featuring a double-stage design with an unloading valve, with a standard pressure setting of 50 bar and the same RPM range.
Additional Products: Other gear pump series mentioned include GHM, ALM, ALPC/GHPC, and ALP/GHP, each offering unique features for different industrial applications, such as high pressure, modularity, and noise reduction.
Design and Construction: Constructed with high-resistant aluminium alloys and special steel gears, ensuring durability and efficiency. The design minimizes noise and pulsation, with special seals to reduce internal leakage.
