1. General Description
The NVM(R) Vertical sump pump casing are made of wear-resistant metal. The wear parts are made of high chromium for the NVM series and are rubber lined for the NVR series. The sump pump could operate under the best condition with different speed. NVM(R) series pumps are centrifugal, vertical slurry pumps submerged in sump during operation. They are designed for delivering highly abrasive, large particles and high density slurries. The NVM(R) series sump pumps are suited for handling abrasive or corrosive, dense slurry with large particle size. 
2. Introduction 
NVM(R) series pumps do not need any seal and the seal water,they could work normally even if the suction volume is not enough with the special cantilevered design.The pumps are of single casing structure with the advantages of light weight, small volume, easy installation and maintenance and so on.
NVM(R) series Vertical sump pumps have different length of shaft to adjust the different depth of pool. According to liquid surface of the slurry pool, the vertical slurry pump transmission shaft and suction pipe could be selected.The suction of pump can also be installed a blender to improve the transfer efficiency..
