How do I choose a hydraulic gear pump?

Judgment of rotation direction of one-way gear pump:

1. Since the one-way gear oil pump has a unique rotation direction, using the wrong rotation direction will damage the internal parts of the product, so the rotation direction of the product must be correctly judged before use.

method 1:

Judge according to the hydraulic pilot pump nameplate.

① Face the nameplate of the hydraulic gear pump towards yourself and observe the arrow mark on the nameplate.

②When the arrow on the nameplate points to the right, the rotation direction of the gear pump (motor) is left-hand (counterclockwise code: L).

③When the arrow on the nameplate points to the left, the rotation direction of the gear pump (motor) is right-hand (clockwise code: R).

Method 2:

Judgment based on matching motor (engine)

①Facing the motor (engine) power output shaft, observe the rotation direction of the power output shaft

② When the rotation direction of the power output shaft is clockwise, the matching gear pump rotation direction is left-hand (counterclockwise code: L).

③When the rotation direction of the power output shaft is counterclockwise, the matching gear pump rotation direction is right-hand (clockwise code: R)

Method 3:

judge based on the actual object.

Note: Under normal circumstances:

One-way gear oil inlet > oil outlet

Oil inlet < oil outlet of one-way gear motor.

① Correctly determine the oil outlet of the gear oil pump (motor), place the oil outlet facing you, and observe the shaft extension of the gear oil pump (motor)

②When the shaft extension is located on the left side of the oil outlet (as shown in Figure 1), the rotation direction of the gear oil pump (motor) is left-handed (counterclockwise code: L).

③When the shaft extension is located on the right side of the oil outlet (as shown in Figure 2), the rotation direction of the gear oil pump (motor) is right-hand (clockwise code: R).

2. Common installation dimensions

1. The mounting flange and shaft extension dimensions are in accordance with the requirements of GB/T2353-2005

2. The type and size of the threaded connection port shall comply with the requirements of GB/T2878-1993

3.SAB installation standards
