Roots Pump PN 11731 Vacuum Pump Repair, Maintenance WA/WAU501

Roots pumps WA/WAU 501 standard series rotary lobe blower vacuum pumps are driven by an air-cooled motor. They have shaft seals that lead to the atmosphere and the pump is connected to an air-cooled motor. WAU pumps are easy to operate! They include a differential pressure valve that allows them to start at the same time as the roughing pump. If the pressure difference between the flanges is too high, the valve will open. And then a portion of the pumped gas flows through this line back to the intake flange. Therefore, the pump may be turned on at atmospheric pressure with the backing pump. This increases the pumping speed of the pump combination at high intake pressures

Detailed introduction:

RUVAC WA series roots pumps are equipped with air-cooled standard three-phase motors directly connected by flange, and the radial shaft seal made of FPM (FKM) is oil-lubricated to achieve shaft sealing against external atmospheric pressure.

Roots pump WAU 251

Roots pumps - reliable, safe and durable

Proven technology

 has been manufacturing RUVAC series roots pumps for decades, and this dry compression technology has proven itself to be suitable for many vacuum applications.

When used in tandem with an oil or dry backing pump, the rotary booster can significantly increase the pumping speed of the system and increase the vacuum that the system can generate, thereby extending the operating range of the backing pump. roots pumps are available in 3 series: the WA series with air-cooled flange motors; WS series with tank air-cooled motor; The WH series adopts a fully sealed water-cooled motor. Each series contains different pumping speeds for different applications. All three series of roots pumps are available in versions with or without bypass valves, also known as pressure balancing valves.

 

■ RUVAC boosters can be used for horizontal or vertical flow installation, which increases the flexibility of the system and the installation position can be changed during installation.

■ The bearing of RUVAC Roots pump and its durability, connected to it is the efficient lubrication system of Roots Pump, which ensures the quiet and stable operation of Roots Booster.

■ WS and WSU series roots pump motor, rotor is sealed by the tank in a vacuum separated from the stator.

 

Since no drive shaft is connected from the outside to the inside, the rotor can be optimally sealed in a vacuum.

Thanks to an efficient lubrication system, the WS series roots pumps can run at speeds of up to 6000 RPM

This means that the WA(U) series can achieve higher pumping speeds for the same size vacuum pump while meeting the IE3 energy efficiency requirements
