Product Description
Product Introduction
The ZGD Screw Self-Priming Pump stands as the epitome of miniature water pump technology, combining a water pump, motor, and advanced sealing into one cohesive unit. Powered by both single-phase and three-phase asynchronous motors, the pump features a uniquely designed spiral impeller, which creates an original cavity that allows for impressive self-suction capabilities. The pump and motor are connected with a single-end mechanical seal, while an O-type durable oil-rubber sealing ring ensures a reliable static seal.
Usage Conditions
To ensure optimal performance, the electric pump must operate continuously under the following conditions:
1. The medium temperature should generally not exceed +40°C;
2. The pH value of the medium should range between 6.5 and 8.5;
3. Solid impurities in the medium should not surpass a volume ratio of 0.1%, with particle sizes no larger than 0.2mm;
4. The power supply frequency should be 50Hz, with a single-phase voltage specification of
220V. The voltage fluctuation should remain within 10% of the rated value.
Overview
The ZGD Screw Self-Priming Pump represents a groundbreaking fusion of a water pump, motor, and sophisticated sealing technology in a compact form. The single-phase and three-phase asynchronous motors drive a spiral-structured impeller that excels in self-suction due to the original cavity design. A single-end mechanical seal pairs the pump with the motor, complemented by an O-type durable oil-rubber sealing ring for static sealing.
