Product Description
Product Description |




Main Feature |
· Large pumping rate over a wide pressure range. Like an "accelerator" acting on the front pump to increase its pumping speed and limit vacuum. · There is no friction in the running parts of the pump, no need for lubrication, no oil in the pump chamber, and clean vacuum can be obtained.
· The gas in the pump chamber flows vertically, which is conducive to the removal of dust and condensate in the pumped gas. · Fully symmetrical and finely balanced rotors operate smoothly and reliably.
· Prevent oil leakage and emulsification -- Use of shaft extension mechanical seal and composite seal structure design. · Low vibration and noise.
According to customer demand, other materials can be made
