MQS Series Self-Priming Pump with Aluminum Motor Casing
MQSSeries Self-Priming Pump with Aluminum Motor Casing
The MQS seriesself-priming pump with copper impeller cover has a compact structure, while the pump and motor are close-coupled. We could design and manufacturevarious kinds of such pumps to fit for different regions and workingconditions, so these household water pumps exhibit a long service life and a high price performance ratio.
Features of the Self-Priming Pump
1. Our self-priming pump has a small footprint, but it delivers stable performance as expected.In addition, it doesn't require any further adjustment after installation.
2. The inlet port and outletport both adopt flange connection, which ensures convenient pipeline layout andsimple pump installation.
3. The pump and motor share one shaft, and the axial dimension is short. As aresult, this single-phase self-priming pump is able to work steadily with a low noise level.
Operating Condition
1. Ambient temperature: Up to 40°C
2. Liquid temperature: Up to 60°C
