The pump body is made of gray cast iron , which has the advantages of good plasticity and high tensile strength; the pump impeller is made of PPS high-performance plastic, which has a small impact on the pump shaft and is easy to form to ensure pump's good performance.
Every 300 hours the water pump works, it is necessary to inject general-purpose lithium-based grease into the bearing grease cavity to ensure that the grease occupies 1/3-2/3 (about 120g) of the grease cavity to ensure good lubrication of the water pump bearings.
When the water pump is in use, the leaking hole may leaks slightly. At this time, observe whether it leaks continuously . If the leakage does not exceed 3 drops per minute (a quantitative calculation is 0.1ml/min), please continue to use it. The pump will stop leaking in a few days.
