Inquiry (采购产品): Vacuum Pump Solution Moretrench is a specialty heavy construction contractor. One aspect of our business includes groundwater control where we own and operate dozens of wellpoint pumps. The basic function of a wellpoint pump is to pump both air and groundwater utilizing both a vacuum pump and a centrifugal water pump (and there are many other variations). We have historically belt driven the vacuum pump off a diesel engine, I have seen an in-line right angle drive or direct drive off the back of the engine (where the RPM’s match up). The pumps are also often fitted with a horizontal TEFC motor rather than a diesel engine. We have also used ‘self-contained’ vacuum units. Historically we have used oil lubricated, rotary vane pumps (Massport, Becker and others). With the work place becoming more sensitive to environmental issues, the smoking from oil lubricated pumps is increasingly objectionable. Carry over through the vacuum pump can be costly to clean up (recently we spent $50k on such a clean up). We are looking for alternatives. The vacuum pumps we use are generally 100-200 SCFM @ 28” Hg. We are considering oilless vacuum pumps; however we have no experience with these types of units (durability, what if there’s water carry over). We are considering liquid ring pumps; however the source for seal water is the raw groundwater OR we need to recycle to a water reservoir. (Often the groundwater and vapor is contaminated with VOC’s or other material). We do not wish to use potable water as the seal water.
