Installation order reverse order of removal, note that: after the impeller cap fight fight tight, check the gap between the pump impeller and mortar pump, this gap requires about 2mm. After installing the pump cover, check the clearance between the impeller and the pump cover (from the outlet of looking in), this gap should guarantee about 2mm, high temperature medium pump, this gap should be around 2.5mm. The gap between the impeller and the pump fail to meet requirements, can be adjusted by shims between impeller and shaft sleeve. Pump cover and impeller mainly the gap between, can be adjusted by shims between the pump and the pump cover. 2 with pay impeller pump (inlet diameter> 125mm pumps) mortar pump noise characteristics: high molecular weight polyethylene impact energy-absorbing plastic in the highest value mortar pump supplier, good silencer so during delivery reduce the maximum liquid flow generated noise. Safe, toxin: the pump using ultra-high molecular weight polyethylene (UHMW-PE) chemical properties of extremely stable mortar pump specifications, therefore also suitable for use in the food industry. Low coefficient of friction: the internal pump friction coefficient of only 0.07-0.11 mortar pump supply, it has a self-lubricating. In the water-lubricated conditions, the dynamic friction coefficient is lower than PA66 and POM (POM) half. When the form of a sliding or rotating work even better than steel and brass plus lubricant after lubrication.
