ELRO® Pumps for hazardous materials GUP 3-1,5 and GP 20/10Ex

1.0 General

ELRO®Peristaltic pumps GUP 3-1.5 as well

as GP20/10Ex are dimensioned as pumps

in accordance with chapter 1, article 1, sec-

tion (2), paragraph (j), point (ii) of the pres-

sure equipment directive and are therefore

no pressure equipment as dened by the

EC pressure equipment directive 2014/68/

EEC.

The following instructions refer to the pump

for hazardous materials GUP 3-1,5 acc. to

DIN 14427 and GP 20/10Ex.

1 Mains plug with holding clamp

2 Pulsation damper

3 Connecting cable 1.5 m

Caution!

Since the pumps will be used

in combination with other

assemblies, such as motors,

you must also strictly observe

and comply with the operating

and maintenance instructions

for these components as well as

the corresponding notes on safe

and reliable operation.

These on-hand instructions contain

information for installation, operation and

maintenance of ELRO pumps for hazardous

materials.

ELRO® Pumps for hazardous materials GUP 3-1,5 and GP 20/10Ex

Pumps for hazardous materials GUP 3-1,5

and GP 20/10Ex

You should therefore thoroughly read these

instructions before use and always follow the

information contained therein.

All personnel involved in

activities on pump or equipment

associated with the pump

must have read this manual,

especially the chapter ”Safety”

before starting work. This is

too late once work has started.

This applies especially for

persons who work on the

pump only occasionally, e.g. for

maintenance and cleaning work.

You should always bear in mind that a

correct function, a long lifetime and optimal

operational reliability of the pump mainly

depend on

n correct installation

n correct commissioning

n and proper maintenance.

Enquiries concerning service, spare parts

or repairs should be addressed to the

manufacturer or an authorized dealer.

Always provide the following information:

n Type

n Serial number of pump

This information is stamped on the

identication plate on the outside of the

pump.

When returning pumps or pump

parts to the manufacturer or an

authorized dealer for repair or

overhaul, the delivery must be

accompanied by a certicate

stating that the pump is free of

product or other aggressive or

hazardous substances.

1.1 Warranty

The correct function of each ELRO pump

for hazardous materials is checked in the

factory before shipment. The manufacturer

assumes warranty for his product as

specied in the eective terms of sales

and delivery. Faults resulting from the non-

compliance with the regulations and notes

described hereunder can only be rectied at

the cost of the customer.

1.2 Transport

In order to avoid any problems you should

n check the delivered goods against the

delivery note for completeness and

correctness,

n check whether the corresponding

manual for the electric drive has been

included.

Be careful when unpacking the pump and

proceed as follows:

n Examine the packaging for transport

damage.

n Take the pump carefully out of the

packaging.

n Examine the pump for any visible

damage.

Consider the indicated weight

before attempting to lift the

pump. Use only lifting gear of

appropriate capacity.

Do not step or stand under

suspended loads.

Description of safety symbols under

Chapter 2.5.

Caution!

ELRO® Pumps for hazardous materials GUP 3-1,5 and GP 20/10Ex

Attach the lifting tackle so that the pump

for hazardous materials can be safely lifted

(Fig. 2).

Either fold out the carrier handles and carry

the pump by these handles

attach carrier belts or ropes to the eyelets

on the carrier frame and lift the pump with a

hook.

In order to avoid slipping of the

sling the rope (belt) must be

crossed over at the hook.

Fig. 2 Transport of the pump with lifting gear

The priming properties of the peristaltic

pump are based on the vacuum backed

restoring forces of its hose. Due to its paten-

ted design a vacuum is permanently gene-

rated inside the hose on the suction side of

the pump. This vacuum always restores the

hose to its original size.

The abutment 2 (Fig. 3) is an elastomer part

and is installed in the pump section where

the hose is squeezed to maximum extend.

This "soft contact base" of the hose pro-

longs its lifetime considerably.

At the same time this abutment protects the

pump housing against damage caused by

solid particles in case of a hose breakage.

In case of wear the abutment can be easily

replaced.

Saugseite

Caution!

ELRO® Pumps for hazardous materials GUP 3-1,5 and GP 20/10Ex

The sliding tube of the rotor enlarges the

volume of the suction area (4). At the same

time the pressure area (7) is decreased and

the air is forced out through a channel in the

pump cover.

The rotor (1, Fig. 5) rotates inside the

separating part (3, Fig. 5), which is tightly

bolted to the housing. This separates the

suction area (4, Fig. 5) from the inside of the

pump (5, Fig. 5).

The separating part 3 (Fig. 3 and 5)

separates the suction area (4, Abb. 4)

from the inside of the pump (5, Fig. 4) and

protects the pumping hose. In case of hose

breakage it additionally protects the rotor (1,

Fig. 4) against damage caused by abrasive

or coarse particle product. The separating

part can be replaced by simply unscrewing

two screws.

The pump is lled with 1 litre of sliding uid

(glycerine or silicone), which works as

lubricant, barrier and coolant.

The vacuum gauge connected with the

suction area (4, Fig. 4) not only shows the

present suction lift of the pump, but has the

additional function of a warning instrument

for possible defects. If the vacuum gauge

does not indicate a vacuum during

operation, the pump needs to be serviced

urgently.

This maintenance can be carried out without

any special tools.
