RVP Hydrodynamic Coupling Dry Roots Vacuum Pump: 
RVP hydraulic coupling roots vacuum pump with the front stage vacuum pump, can form a large flow, high vacuum system. Roots vacuum pump to increase the pumping speed of the system, improve the role of vacuum. AfaPa roots vacuum pump adopts international advanced hydraulic transmission technology, can automatically change speed, can start under atmospheric pressure, or start and stop at the same time with the front pump, simplify the system configuration and operation process, greatly improve the reliability of the system.

1. Hydraulic transmission structure can make AfaPa pump directly start under atmospheric pressure or high pressure difference;
2. Roots pump can start and stop at the same time as the front pump;
3. Roots pump can automatically adjust the speed, will not produce overload or overheating phenomenon;
4. Roots pump starts in advance under large pressure difference, can reduce the pumping time, improve the pumping efficiency of the system;
5. When the foreign body enters the pump chamber or the pressure changes suddenly, the speed can be automatically reduced to protect, and the shutdown failure rate is very low.
6. Simple configuration, no bypass pipeline, valves and frequency converter, cost saving, easy control
7. Reliable shaft seal structure ensures that grease will not enter the pump chamber.
Q1: If I want to inquiry, what can I need to offer?
A1: Please tell us your Working Vacuum Degree(Pa,mbar or torr), Flowrate(L/S or M3/H) and Usage.
Q2: Do you have MOQ?
A2: 1Pcs is ok,if you have more quantity, the price will be cut down.
Q3: How long to delivery?
A3: We need about 4-5 weeks to produce,then extra need about 5-7 days to arrange domestic delivery and port clearence.
Q4: What is your payment term?
A4: 50% for prepayment, then the balance should paid before delivery, by TT.
Q5: How long for the warranty?
A5: 1 year for whole machine, the effective date of warranty should be counted from one month the goods arrived in client's site. If the pump go wrong, the client can choose back the pump to factory repair,or we offer remote technical support.
