Instrument introduction:in order to promote the further development of two-stage rotary vane pump, Welch Wye company produces more durable, cost-effective, simpler and environmentally friendly direct connected rotary vane pump crvpro series. The advantages of this series are: 1. The operating temperature of the pump body is low, which can effectively reduce the risk of chemical corrosion of the pump. 2. The oil tank and pump body are coated with anti-chemical corrosion coating, which can protect the pump from chemical erosion. 3. The oil tank has a large capacity, which can dilute the chemicals sucked into the vacuum oil, reducing the risk of chemical corrosion and the degree of oil pollution. 4. Low noise: the operation is very quiet and does not interfere with the work. 5. Self lubrication function: ensure that all moving parts are soaked in fresh oil, balance the temperature, reduce oil pollution and prolong the mechanical life. 6. Anti back suction valve: prevent the oil from being sucked back into the vacuum container during shutdown. 7. Pneumatic carrier valve: reduce the entrainment of chemical steam into the pump oil; Protect the pump from the influence of condensable fluids such as water and acetonitrile. 8. Cul and CE certification: it has national safety certification and meets official safety standards. 9. Meet the overall dimensions of various applications: Modern and compact overall design to meet the requirements of various applications. 10. Dual voltage motor: IP44 motor, which can be switched between 115V and 240V, and can be configured with various corresponding power plugs to make crvpro usable.
