Buy & Import Double Pump from Dongfang Yoyik Engnieering Co., Ltd. - Wholesale Supply

The Double Pump GPA2-16-16-E-20-R6.3 is a dual-circuit hydraulic pressure pump designed for industrial power systems, specifically compatible with steam turbine and boiler auxiliary circuits. It operates at a maximum pressure of 31.5 MPa, with a nominal flow rate of 20 L/min and a drive speed of 15000 rpm. The pump features a bladder accumulator with a 20-litre capacity, 197 mm diameter, and 900 mm length, paired with a 30 mm NBR sealing port and a solenoid valve model 4WE6D62/EG110N9K4 for precise pressure control.

This pump assembly integrates components typical of heavy-duty power plant hydraulics: the NXQ1-L24.9/31.5 bladder accumulator meets DIN 24311 standards for high-pressure energy storage, and the roller press nitrogen airbag NXQA-40L/31.5-L-A is engineered for cyclic loading in turbine systems. The mechanical seal BGM37G/60R-G9 and the stop valve J61H-100 25 are rated for continuous operation under high thermal stress, with materials selected for resistance to hydraulic fluid degradation and abrasion.

Buyers in power generation, heavy machinery, and industrial maintenance sectors source this pump for replacement in aging turbine control units. It is commonly used in plants requiring redundant hydraulic pressure circuits. Trade terms are typically FOB Qingdao or CIF destination, with packaging in wooden crates reinforced for vibration protection. Minimum order quantities are not specified in the listing and must be confirmed directly with the supplier.
