Overview
The Edwards RV pump has become the industry standard in the science of single-stage pump applications. The RV pump is uniquely characterized by its ability to provide high or low flow rates with high ultimate vacuum. This feature, combined with its extremely low noise, makes it the ideal product for a wide range of applications, including GCMS and other small benchtop applications.
All pump products are tested by external testing institutions and meet UL and CSA standards. Edwards has a global network providing product applications and support worldwide.
With product provided: 1 liter of Ultragrade 19 oil, intake filter, and O-rings. Fomblin® must be purchased separately for the PFPE RV pump.
Features and Advantages
48 dB(A), reduces the intrusive frequency to a significant degree.
Dual-mode. Suitable for high throughput and high vacuum applications.
Easy-to-use airbags.
The quick-acting inlet valve provides protection for the system.
High torque, dual pressure/dual frequency motor, electric start relay.
High-efficiency high-pressure lubrication.
Sealed oil seals with printed shims, high shaft sealing efficiency.
Insertable observation window.
High-tech polymer blades, large diameter, oil channels easy to clean.
Consistent inherent quality, cast bar structure.
Gas Regulator
The dual gas trap can handle 60 g/hr of steam, or more than 220 g/hr of steam compared to similar products (290 g/hr on RV12). When used in combination with a return oil attachment and an oil mist filter, it can continuously extract and pump without reducing lubrication. After installing an optional solenoid-operated gas trap valve, the gas trap can operate automatically.
Motor
A single universal motor covers the widest voltage and frequency range. The single-phase motor features an external switch, allowing adjustment from the high voltage range (220-240 V) to the low voltage range (110-120 V). The universal three-phase motor is also suitable for all models. For special applications, we can provide pumps equipped with ATEX-certified explosion-proof motors.
Entrance
Top-grade backflow protection
Maintain stable control of the open state through hydraulic pressure, thereby eliminating pressure fluctuations.
Within the 0.4 seconds of the pump stopping due to the drain valve, quickly shut down.
All Edwards RV pumps are equipped with inlet seals and integrated inlet screen filters.
VacuumOil
The Edwards RV pump is originally filled with Ultragrade 19 oil. This high-quality oil, specifically formulated with a series of unique additives, delivers superior vacuum performance over any other mineral oil. As a result, it can provide both a strictly controlled steam pressure and exceptional antioxidant properties, leading to a longer service life. For oxygen-rich applications, we offer pumps equipped with PFPE. For pumps with PFPE, Fomblin® must be purchased separately.
Designed for easy maintenance
Hexagonal head wrench with uniform size for disassembly of all parts
All parts are self-aligning, so no supports or special components are required.
Polymer blade without springs or pins for easier assembly and higher reliability
The shaft seal can be replaced on the motor side without dismantling the pump assembly.
There are no O-rings between the slices, making assembly easier.
All parts are interchangeable, so they can be ordered individually.
Mode Switch
The unique selector switch patent technology allows a single pump to be suitable for various applications, thus enabling you to use just one model for both high vacuum and high exhaust volume applications.
In high-vacuum mode, the selector switch increases oil flow to the high-vacuum stage, enabling the pump to run continuously at high inlet pressure without any wear or reduction in lubrication.
