■ Overview

VOLM 2BE1 series vacuum pump exhaust system takes in a unique PTFE valve plate structure (the original one is ball valve structure). It is covered on the outside vent hole of the disc and is positioned by stainless steel baffle on the other side. The valve plate changes its bending degree with the change of the inlet pressure so that the pumping medium can be exhausted when reach the customized inlet pressure. This structure avoids overcompression in the vacuum system, which automatically adjusts the exhaust area to reduce energy consumption, so as to result in optimum operating efficiency. This series of pumps are with single-stage single-action structures, having the advantages of simple structure, easy maintenance, reliable operation, energy efficient and so on. Compared with the current widely used SK, 2SK, SZ series of water ring vacuum pump, this series have advanced technology, high vacuum, low power consumption, reliable operation and other significant advantages, and are ideal alternative products.

■ Features:

● Upper-type gas water separator design, saving space and reducing noise effectively.

● Reserved suction and exhaust flange on the side makes installation simple and convenient.

● All bearings are imported from Germany, ensuring stable space between impeller and the disc, accurate positioning of the impeller, high stability and sustainability of equipment during the operation.

● The sleeve is made of high chromium stainless steel to improve the service life.

● Pump pulley and clamping set takes the implementation of export standards.

● Diverse material selections of pump body, high-precision CNC machining.

● Castings are manufactured according to export standards, all use resin sand casting, annealing treatment.

● Ductile iron casting or steel plate welding and high temperature solid solution are used for all impellers, which ensure the stability of 2BE1 vacuum pump impeller working in a variety of harsh conditions and improve the service life of 2BE1 vacuum pump.

● Mechanical seals (optional) are all imported parts.

● Vacuum pump parts can be exchanged with the same model ones of the foreign equipment.

●The supplying range of pumps can be flexibly chosen according to customers’ requirements:

Pump head: including the upper-type separator, connecting pipe.

Whole set of the machine: including the pump head, the upper-type separator, connecting pipe, motor, chassis, hood, pump and motor connector or pump pulley, belt.

Vacuum pump unit: including vacuum pump machine, gas-water separator, check valve, bellows and connected piping, electrical contact vacuum gauge, auto-decompression starting cabinet.

Complete sets of equipment: including the whole set of vacuum pump machine, gas-water separator (with level gauge), heat exchangers, valves, normally closed valves, filters, vacuum gauge, pressure gauge, pipe, electric control cabinet.

Inlet pressure below 33 mbar (absolute), 2 stages or multi-stages vacuum system (water ring - Roots unit) will be in use.

● Varied transmission methods, such as: Coupler driving, pulley driving, reducer driving.

● Stainless steel materials (304, 316L) or special ones can be chosen according to the corrosion of media; Packing seals and mechanical seals or others can be provided on request.

■ Applications

2BE1 series of products have a wide range of applications, such as the condenser vacuum suction, desulfurization device in fly ash treatment, acetylene and other flammable and explosive special gas compression, ozone compression, pulp and paper, gas recovery, soil purification, disinfection , dehydration, Filtration, extrusion / vacuum forming, dipping, extraction, pressure swing adsorption decarbonization, hydrogen extracting, oxygen producing, purification and so on.
