    This manual provides installation, operation and maintenance instructions for the Edwards dry claw pump. Edwards takes no responsibility for damage or injury caused by improper use of the equipment. Read this manual before you attempt to install, operate or maintain the dry claw pump.

  • Page 6: Safety Precautions During Installation

    Place the machine where the ambient air is as cool and clean as possible. Never obstruct the cooling air inlet. Water handling capacity is limited. For operating in such applications, consult Edwards. Any blanking flanges, plugs, caps and desiccant bags must be removed before connecting the pipes.

    13. Never run the overpressure pump without the air intake filter mounted. For the vacuum pump, Edwards recommends to install an air intake filter to safeguard the pump. Consult Edwards to check whether the application for the vacuum pump requires and air intake filter.Never remove or tamper with the safety devices.

  • Page 10: General Description

    There are two common but different ways to denote flow rate in vacuum. The first one is based on the displacement or volumetric flow rate and the second one is based on the throughput or mass flow rate. Edwards vacuum pumps use volumetric flow rate to denote performance, the unit being Am³/hr. © Edwards Limited 2016. All rights reserved.

  • Page 11: Introduction

    The motors are suited to operate with Variable Speed Drive to have complete controllability and to reduce power consumption. This efficiency improvement leads to power reduction and consequently a lower carbon footprint. © Edwards Limited 2016. All rights reserved.
