1, Two big vents on the two sides of the industrial vacuum pumps for inspecting the gap, corrosion and other conditions.
2, All bearings import from Japanese NSK to ensure the precise orientation of impeller and high stability during the running.
3, The material of the impeller is welded with nodular iron or stainess steel to ensure the high stability and increase the lifetime of the industrial vacuum pump greatly during any harsh conditions.
4, The cast iron or stainess steel pump body improve the lifttime.
5, The shaft sleeve as the most easily damaged part, we use the stainless steel material to increase the lifetime more than 5 times than normal material.
6, The pulley (when the industrial vacuum pumps for sale is driven by the belt) use the standard high precise taper bushing pulley to keep the reliable running and increase the lifetime; also it is easy to dismantle.
7, Special separator built-on the industrial vacuum pump for sale can save the space and reduce the noise efficiently
8, All the parts are cast by the resin sands with great quality, no puttying. Keep the heat dissipation is the best
9, Import all the mechanical seals (optional) to fully ensure the vacuum pump for sale in the long-running process without leakage.
