2.2 Proper use

EachLutzeccentricscrewdrumpumpofseriesHDSS41-E-MSandHD-SRSS41-E-MSconsistsofauniversal,

single-phase or compressed air motor and a pump tube.

The apparatus is provided for commercial use only.

• Pumpisnotallowedtobeoperatedinexplosionhazardareas.

• Donotuseforpumpingammableliquids.

• Pump may only be installed in an upright position.

• Pump may only be used on roofed surfaces or in roofed and

closed rooms.

• The pump may only be used to pump the agreed liquids

(→ Contract data sheet) or ensure that the pump is resistant to

the liquid being pumped (→ technical data, →Lutzresistance

table).

• Note the limit values for temperature and viscosity of the liquid

being pumped (→ technical data).

• The drive motor must be located outside of the mobile container

or drum (→ Fig. 1).

• The pump may only be operated with the discharge closed, if a

bypass valve with return line has been installed.

• Ensure that the safety valves for the protection of the pump

against inadmissible increase of pressure are not higher set than

the maximum operating pressure (→ technical data).

• The pump is not allowed to run dry. This must be permanently

controlled by the operator.

If the product and supplied accessories are used for other purposes than the intended purpose, it is the

responsibilityoftheusertocheckthesuitabilityandadmissibility.Productusenotconrmedinwriting

by the manufacturer absolves the manufacturer of any liability.

The manufacturer is not liable for consequences of incorrect treatment, use, maintenance, servicing and

operation of the appliance, as well as normal wear and tear. The same applies if faults arise from intervention

orcongurationsonthepartoftheusernotconrmedbythemanufacturer.

Any other use is not an intended use.

2.2.2 Prevention of obvious misapplication (examples)

• Observe and comply with the operating limits of the pump in terms of temperature, pressure,

delivery rate and speed (→ contract data sheet, → technical data).

• The power consumption of the pump increases with increasing viscosity of the pumped liquid.

With the type HD-SR Niro 41-E-GLRD the speed increases with decreasing viscosity. Observe the

permissible viscosity range(→ technical data) to avoid overloading the pump, gear, coupling and

motor.

• Do not use the pump tube to lift objects.

Dangerous media

• Whenpumpingdangerousuids(e.g.hot,poisonous,dangeroustohealth)observethesafety

regulationsforhandlinghazardoussubstances.

• Always wear protective equipment when working on the pump.

4.1 Transport

Unpacking and checking condition of delivery

► Unpack the pump tube on receipt and check for transport damages.

► Report transport damages to the manufacturer immediately.

► Check that the consignment is complete as ordered.

! WARNING

Danger of injury by falling objects!

►Beforetransport,thewingnutandhandwheelmustbermlytightened.Otherwise,thetubemay

release from the pump tube and fall on people nearby.

► When transporting with lifting equipment, ensure the proper use of the lifting equipment. Observe the

operating instructions of the lifting equipment. Do not stand under the pump.

4.2 Storage

! WARNING

Danger of injury and intoxication when handling hazardous liquids!

►Always wear protective equipment when working on the pump.

►Complete emptying of pump tube.

►Store pump at a protected place.

5. Installation/Assembly and connection

5.1 Connection to the motor

! WARNING

Danger of injury and intoxication when handling hazardous liquids!

► When mounting the motor on the pump tube, hold the motor in such a way that no limbs can be

squeezedbetweenthemotorandthepumptube.

5.1.1 HD SS 41-E-MS

3Motorisswitchedo

►The motor is mounted on the pump tube.

The motor must be turned slightly to ensure that the driver

engages correctly in the coupling of the pump tube. The motor

andpumptubearethenrmlyconnectedbymeansofthe

handwheel (right-hand thread) (→ Fig. 2).

5.1.2 HD-SR SS 41-E-MS

3Motorisswitchedo

► Attach the pump motor onto the pump tube (→ Fig. 3). The

motor must be turned slightly to ensure that the driver engages

correctly in the coupling of the pump tube. Connect the motor

and the pump tube with the hand wheel (right-hand thread).

►Ensurethatthepumpisttedcorrectlyandsecurely.

5.2 Notices regarding start-up

! WARNING

Risk of injury by crushing!

►When inserting the pump tube into a container, position your hands in a way that no pinching between

the pump tube and the container can happen.

► Wear protective gloves.

5.3 Electrical connection

3 Mainsvoltageandfrequencyareasspeciedontheratingplate

(→ Fig. 4).

3 Before connecting the pump to the power supply set switch in

OFF position.

5.4 Connection of compressed air motors with

HD-SR SS 41-E-MS

The required air pressure depends on the viscosity of the pumped

liquid. Higher viscosity requires higher air pressure.

For the motors MD1xL and MD2xL, an air pressure of at least 1 bar and

an air consumption of 300 Nl/min are required with water.

5.5 Mechanical loads on the pump tube

The pump tube’s functioning and service life are impaired when

deformed by mechanical loads. For this reason, the outlet must not

be subjected to compressive or tensile forces.

► The bending moment MB at the outlet must not exceed 30 Nm

(→ Fig. 5).

Fig. 4

Fig. 5

0697-251 HD-E, HD-E-SR - 11/2022

5.6 Maximum immersion depth

► Make sure that the pump is not submerged further than its

discharge port (→ Fig. 6).

5.7 Assembly in the container

► Fasten the pump in the container. Make sure that the container with the installed pump is enough stable

even in empty condition. This is of special attention with small containers.

6. Operation

3 Allconnectionsandttingsareproperlytightened.

! WARNING

If connections are not properly or not at all tightened:

- it can come to splashing medium.

- itcancometoyingparts.

- the pump may start moving in an uncoordinated manner.

! WARNING

Danger of injury and intoxication when handling hazardous liquids!

►Always wear protective equipment when working on the pump.

forhandlinghazardoussubstances.

Fig. 6

0697-251 HD-E, HD-E-SR - 11/2022

6.1 Dry running

► The pump is said to run dry if it continues to operate without pumping any liquid whatsoever. Dry

running must be avoided. This can be ensured by remaining in attendance or with the aid of such

technicalmeansasaowmonitor,etc.

6.2 Suction funnel

►At least the suction openings must be completely covered with the medium in order to prevent the

inltrationofairwhilepumping.Whenpumpinghighlyviscousproducts,caremustalsobetakento

prevent the formation of suction funnels.

6.3 Operation with closed discharge

! WARNING

Injury by ying parts!

The eccentric screw pumps HD SS 41-E-MS and HD-SR SS 41-E-MS are positive displacement pumps.

Thepumpmustnotbeoperatedagainstclosedshutodevices,suchasnozzle,valve,etc.Anexcessive

pressure build-up may result in damage. Make sure that the maximum pressure will not be exceeded

(→technical data).

6.4 Malfunction

! WARNING

Pinching by rotating parts!

► In case of malfunction or unreproducible downtime, disconnect the motor from the mains before

repair work is carried out.

6.5 Taking out of operation

! WARNING

Danger of injury and intoxication when handling hazardous liquids!

► Always wear protective equipment when working on the pump.

►Collectanyresidualleakinguidsfromthepumpsafelyanddisposeofitinanenvironmentally
