| New HullVac rotary piston vacuum pump  HullVac Pump announced Next Generation rotary piston high vacuum pumps. These premium quality pumps offer increased pumping speed in a small footprint and novel design features that increase operating life while reducing maintenance needs associated with harsh applications. Purchase price for the 635 CFM displacement pump is less than the cost of two 300 CFM pumps. Ongoing savings are achieved because maintenance and oil usage is significantly less than for the two pumps replaced by one HV635. The innovative design that keeps bearings outboard and away from process contamination also makes the pumps field serviceable.Viton shaft seals riding on hardened sleeves keep process grit from damaging the bearings. Other design benefits include all metal exhaust valves, a large oil sight port with visual oil flow indication and caged hinge bars that extend operating life without the need for costly re-boring. write your comments about the article :: © 2007 Construction News :: home page |
