EVISA Lubricated Rotary Vane Vacuum Pumps - Technical Summary

1. Overview

The document provides comprehensive technical specifications, operational features, maintenance guidelines, and accessory options for the EVISA series of lubricated rotary vane vacuum pumps. These pumps are designed for continuous industrial and healthcare applications, offering robust, silent operation from atmospheric pressure down to ultimate vacuum levels.

2. Specifications and Performance

• Vacuum Capability: Achieves absolute end vacuum levels as low as 6x10^-2 mbar (approx. 4.5x10^-2 torr), depending on model and gas ballast settings.
• Pumping Speed: High pumping speeds across models (E25.R, E40.R, E150.R, E200.R, E300.R), with nominal flow rates ranging from ~25 m³/h to 360 m³/h, measured per PNEUROP 6602 standards at 20°C.
• Water Vapor Handling: Adjustable gas ballast (closed, partially opened, fully opened) allows effective pumping of humid gases and prevents condensation inside the pump.
• Noise Levels: Low noise emissions (from ~44 dB(A) to 77 dB(A) depending on model), enabling installation near operators.
• Oil: Pumps are delivered with MV99S 100% synthetic oil for durability and heavy-duty use; oil capacities vary by model (1 to 2.2 liters for smaller pumps, larger volumes for bigger models).
• Electrical Motors: IE3 efficiency motors with power ratings from 0.75 kW to 10 kW (or 1 to 13.5 HP), available in multiple voltage and phase configurations tailored to geographic regions (Europe, USA, Asia, South America, Middle East, Japan).
• Connections: Standard inlet/outlet connections include 1" or 2" BSP/NPT threads, with optional DN25, DN40, or DN50 ISO-KF flange adapters.
