SQP21-21-14-86DC-18 double vane pump model description, performance parameters

The SQP21-21-14-86DC-18 is a high-performance double vane pump that can replace the imported TOKYO KEIKI TOKIMEC SQP21 double vane pump. The following is a detailed analysis of its model description and performance parameters:

1. Model Description

Brand: YIHE

Series: SQP series, high-pressure and high-performance double vane pumps developed specifically for low-noise working conditions

Model description: SQP21-21-14-86DC-18, where "SQP21" represents the hydraulic vane pump model, "21" represents the geometric displacement of the shaft-end pump, "14" represents the geometric displacement of the cover-end pump, "86" represents the main shaft type is a heavy-duty flat key, "DC" represents the oil port orientation, and "18" is the design code of the oil pump.

2. Performance Specifications

Maximum operating pressure of the shaft-end pump: 172 bar

Maximum operating pressure of the cover-end pump: 138 bar

Shaft-end pump displacement: 65.0 cm³/r

Cover-end pump displacement: 44.2 cm³/r

Speed range: 600-1800 rpm

Weight: Flange mounting type - 31.5kg, foot mounting type - 41kg

Noise: Since the SQP series vane pump is specially developed for low noise working conditions, the noise level of this hydraulic vane pump during operation is relatively low.

Strength and shock resistance: The thickened shell design increases the strength and shock resistance of the hydraulic vane pump, enabling it to maintain stable operation in harsh working environments.

3. Other Features

Pulsation attenuation structure: The design of the pulsation attenuation structure has been added, which greatly reduces the pulsation of pressure, makes the noise lower, and the sound quality beautiful and smooth.

Wide application: This double vane pump is widely used in hydraulic systems requiring low noise, such as plastic machinery, die-casting machinery, machine tools and engineering machinery.

4. Precautions

When using the SQP21-21-14-86DC-18 double vane pump, ensure that the pump is rotated in the correct direction to avoid performance degradation or damage caused by changes in suction and discharge direction.

When assembling the vane pump, the oil distribution plate and stator should be correctly positioned using locating pins, and the blades, rotor and oil distribution plate must not be installed upside down.
