D Series Cast Iron Gear Pump_Gear Pump_Turolla Gear Pump & Motor_Products-Xuzhou Sunwell Power Transmission Machinery Co.,Ltd.

Products

• Wheel loader - Aggressive duty cycles with continuous working pressures above 250 bar [3600 psi]

• Mining equipment - Increased exposure to system contamination in a corrosive environment

• Skid steer loaders - Multiple pump combinations with short length and common inlets

• Work function attachments - Rapid loading of cylinders/motors in high bulk modulus systems causing pressure rise rates greater than 3000 bar/sec

• Agricultural sprayers - Pumps with integrated valves including priority flow dividers and load sense steering

• Pavers - D pumps integrated with other TurollaOCG components including variable displacement piston pumps, aluminum gear pumps and cartridge valves

• Fan drives - High levels of performance with elevated temperatures and minimal oil viscosities and restrictive envelope dimensions
