2 General description

2.1 Overview

WARNING: INCORRECT USE OF EQUIPMENT

Risk of injury or damage to the equipment. Incorrect use of the equipment can cause

damage to the equipment or injury to people. The user is responsible for the safe

operation, installation and monitoring of the system.

The ECODRY plus product family is a range of dry, multi-stage roots vacuum

pumps that offers high pumping speed in a compact form. The pump is

connected by a power cord and is designed for use on clean duty

applications.

The cord ratings are:

Supply voltage (V) Current (A) Frequency (Hz)

100 ‑127 14 50 or 60

200 ‑240 7

The pump is not designed for use with ammable, corrosive, toxic, or other

hazardous gases. Gas or oxygen can mix in the pump.

The dry pumping system can be used in either transient or steady state gas

load conditions. The pump can sustain continuous operation with a

maximum power consumption of 850 W. When the load is more than 850 W

motor power the speed temporarily reduces.When high load passes the

motor speed is increased, or when the transient overload protection has

recovered. Refer to Table: Performance data for information on maximum

inlet pressure.

Refer to Figure: General view, the system is supplied with an DN 25 ISO-KF

inlet port (1) and an DN 25 ISO-KF exhaust port (10).

The pump mechanism is operated by an electric motor driven by an internal

pump controller. The rotational elements of the pumping mechanism are

simply supported at the end by lubricated bearings. PFPE lubricant is used

and this is contained in both the gearbox and motor ends of the pump

module, these are "sealed for life" and the lubricant does not need to be

replaced until the pump service interval is reached.

The system is air cooled by a fan installed internally in the pump enclosure.

The pump has a thermal protection device that will stop the motor if a

thermal overload occurs, for example due to high ambient temperature. If

the thermal protection is triggered, you must restart the pump after it has

cooled down.

The pump is designed to pump the residual gases used in high vacuum

systems. The gases are:

▪Air

▪Nitrogen

▪Krypton

▪Argon

▪Helium

General description

You can use the pump to pump water vapour. You must use the gas ballast

when water vapour is pumped. The water vapour must not condense in the

pump.

To use the pump for a gas that is not listed, contact the supplier for advice.

Failure to contact the supplier can invalidate the warranty of the pump. Do

not use the pump for aggressive or corrosive gases.

2.2 Pump controller

The pump controller contains the drive electronics to control the pump

operation. The pump controller controls the supply of electric current to the

motor as per the operating conditions.

The interface control panel is connected to the pump controller. The pump

can be operated:

▪manually, with the buttons on the user interface control panel. Refer to

Figure: Interface control panel.

▪remotely, with the serial communications (X104) or digital and analogue

process control (X1), through the SUB-D 9 pin connector. Refer to

Connection for remote control and monitoring on page 23.
