Our Helical External Gear Pump is designed for high flow, large transfer applications and versatility within industrial settings. The external gears feature lower operating speeds and helical (angled) teeth in place of straight teeth, for a gradual operation. Additionally, these pumps are ATEX-approved for use in hazardous environments.
Typical applications for our Helical External Gear Pump:
| Specification | Description |
|---|---|
| Max Capacity (m³/hr) | 250 |
| Max Pressure (m) | 150 |
| Viscosity (cPs) | 55,000 |
| Max Speed (rpm) | 1500 |
| Max Temperature (°C) | 350 |
A horizontal-shaft pump with two external helical gears. As the shaft turns, the gears draw liquid into the inlet, trap it between the gear teeth, and carry it around the casing to the outlet.
A spring-loaded, adjustable valve that protects the pump and drive system from overpressure caused by blockages or closed discharge valves. When pressure exceeds the set point, it opens and recirculates fluid from the discharge side back to the suction side, reducing pressure until normal flow is restored.
