1. Used as oil feed pump and main pump in long-distance pipelines;
2. Used for short-line transportation, such as oil field gathering and transportation;
3. Oil loading and unloading at the wharf.

Speed: 990, 1480 and 2960 r/min.

Voltage: 380, 6k or 10kV

Inlet and outlet diameter: 150~ 600 mm

Flow range: 68~3975 m3/h

Lift range: 10~230 m

Temperature range: Maximum liquid temperature ≤80°C, ambient temperature generally ≤40°C

Maximum working pressure (inlet pressure + pumping pressure): ≤2.5MPa; long-term oil transmission main pump and oil feed pump ≤12.5MPa

For horizontal installation, the driver (electric motor or internal combustion engine) can be set on the left or right side of the pump as needed (that is, facing the outlet, the driver rotates counterclockwise on the left and clockwise on the right).

1. Ordering parameters that must be provided

▲Viscosity, density, temperature, flow rate, and head of the pumped medium

▲Import pressure

▲The direction of rotation of the pump (if it is installed in a clockwise direction, it must be specified, if not specified, it will be delivered in a counterclockwise direction)

▲Motor power, voltage, protection level, explosion-proof level, usage environment conditions

▲Pump casing, impeller, shaft and other parts and materials

2. Selection instructions:

▲User orders are not limited by the parameters listed in the sample performance curve and technical data table. The parameters listed in the sample are only special typical point parameters for user selection reference. The company can provide products according to the flow and head operating points required by the user’s design. The working medium of the technical data listed in the sample is clean water at room temperature. When transporting viscous media, the flow rate, lift, and supporting motor power must be converted according to the viscosity.

▲If the performance parameters are similar, the standard impeller pump type (M type) and the high-speed pump type are generally preferred (but must be able to meet NPSHa requirements).
