Product Description
GR & SMT Series High-Performance Low-Noise Hydraulic Screw Pumps
Product Overview: The GR and SMT Series are the definitive benchmarks for “Ultimate Silence” in modern industrial hydraulic systems. Utilizing unique screw/gear meshing technology, these series are specifically engineered for applications requiring continuous, smooth flow output with stringent environmental noise constraints. This featured range includes specifications from the compact GR28 and GR33 to the heavy-duty GR80, and the high-capacity SMT Series (including 380L, 500L, and 1200L). Their precision-engineered design ensures nearly zero pressure pulsation when delivering various viscosities of hydraulic and lubricating oils, making them the top choice for machine tools and lifting systems.
Key Technical Advantages:
Ultimate Silence & Zero Pulsation: The unique continuous contact line design ensures smooth fluid delivery, completely eliminating the fluid trapping shocks common in other pumps for ultra-quiet operation.
Broad Viscosity Adaptation: Optimized for lubricants, fuels, and hydraulic oils, easily handling viscosity fluctuations to ensure pressure stability across varying temperatures.
Extended Life & Low Maintenance: Minimal friction between moving parts reduces metallic wear, significantly extending maintenance intervals in industrial circulation systems.
High Flow Capacity: Large displacement models like the SMT 1200L provide steady flows up to 1200 L/min, meeting the cooling and lubrication demands of heavy machinery.
Target Applications: Machine tool spindle cooling, elevator hydraulic power units, fuel injection supply, wind turbine lubrication, and silent hydraulic power stations.
