Overview
The Edwards RV pump has become the industry standard for scientific applications in the field of single-stage pumps. The RV pump is uniquely designed to provide high flow or low flow with high ultimate vacuum. This feature, combined with its extremely low noise level, makes it the ideal product for a wide range of applications, including GCMS and other small benchtop applications.
All pump products have been tested by an external testing facility and meet UL and CSA standards. Edwards has a global network providing support for product applications and services worldwide.
With product provided: 1 liter 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 intake valve provides protection for the system.
High torque, dual pressure/dual frequency motor, electric start relay.
High-efficiency high-pressure lubrication.
Printed gasket oil seals, high shaft seal efficiency.
Insertable observation window.
High-tech polymer blades, large diameter, oil channels easy to clean.
Consistent inherent quality, casting bar structure.
Gas Regulator
The two-stage gas trap can handle 60 g/hr of steam, or more than 220 g/hr (290 g/hr on RV12) of steam compared to similar products. When used in conjunction with the return oil attachment and oil mist filter, it can continuously exhaust without reducing lubrication. After installing the optional electromagnetic actuated gas trap valve, the trap can operate automatically.
Motor
A single universal motor covers the widest voltage and frequency range. Single-phase motors come with an external switch, allowing adjustment from a high voltage range (220-240 V) to a low voltage range (110-120 V). Universal three-phase motors are also suitable for all models. For special applications, we can provide pumps equipped with ATEX-certified explosion-proof motors.
Entrance
Top-grade anti-backflow protection
Stabilize and control the open state through hydraulic pressure, thereby eliminating pressure fluctuations.
Within the 0.4 seconds when the pump stops due to the relief valve, quickly close.
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, specially formulated with a series of unique additives, offers superior vacuum performance over any other mineral oil. As a result, it provides both extremely controlled steam pressure and excellent antioxidant properties, ensuring a longer service life. For oxygen-rich applications, we also offer pumps with PFPE. For these pumps, Fomblin® must be purchased separately.
Designed for easy maintenance
Hexagonal head wrench of uniform size can remove all parts.
All parts are self-aligning, thus no supports or special components are required.
Polymers blades without springs or pins are easier to assemble and offer 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
Unique mode selector switch patent technology allows a single pump to be suitable for various applications, thus enabling you to use one model for both high vacuum and high evacuation applications.
In high evacuation mode, the selector switch increases the oil flow to the high vacuum stage, allowing the pump to run continuously under high inlet pressure without any wear or reduction in lubrication.
