Anticorrosion

Anti rust raw materials do not need anti-corrosion.

Please consult the manufacturer for the recommended preservative.

ALL WEILER

Poisoning hazard caused by preservatives and detergents in food or drinking water! Only use cleaning agents compatible with the transport medium (→ 9.2.6 Detergent, 37 pages) Completely remove the preservative.

instructions

Excessive water pressure or water spray will cause bearing damage! It is forbidden to use jet water or steam ejector to clean the bearing part.

instructions

Using the wrong cleaner will cause damage to the seal! Ensure that the cleaner does not corrode the seals.

1. Select the cleaner according to the scope of use. (→ 9.2.6 Detergent, 37 pages)

2. Dispose of preservative according to local applicable regulations.

3. Warehousing time exceeds six months:

– Replace synthetic rubber made of polyester rubber.

– Check the forming bullets of all synthetic rubbers (round gaskets, shaft sealing rings) If necessary, replace it.

instructions

Non professional storage will cause property damage! The pump shall be subject to anti-corrosion treatment and storage as required.

1. Close all openings with non perforated flanges, plugs or plastic covers.

2. For the specification equipped with oil lubricated bearings, and the static parking time exceeds one year:

– Unscrew the storage container

– Unscrew the connecting piece of the oil level regulator

– Close threaded holes

– Fill the bearing frame with oil

– Close the vent

3. Ensure that the warehouse meets the following conditions:

– Dry

– Frost free

– No vibration

4. Run the shaft once a month.

5. Make sure that the shaft and bearing change the rotating position at the same time.

waste disposal

Toxic or radioactive transport media may contaminate the plastic film to a clean level The degree of effectiveness.

warning

Conveying medium or oil will cause poisoning hazard and environmental pollution! Use protective equipment when working on all pumps.

Before disposing of pump waste:

– Collect the leaked transmission medium or oil and divide it according to the local applicable regulations Class processing.

– Neutralize the conveying medium residue in the pump.

– Remove the anti-corrosion (→ 4.4 Remove the anti-corrosion, 15 pages)

Remove the plastic parts and dispose them according to the local applicable regulations. Dispose of pump waste in accordance with applicable local regulations. Installation and connection

instructions

Excessive tension or current in the bearing will cause property damage!

It is forbidden to make structural changes on the pump unit or pump casing.

Welding work on the pump unit or pump casing is prohibited.

instructions

Impurities will cause property damage! Remove the transport safety device immediately before installing the pump. Remove the cover plate, transport cover and seal immediately before connecting the pipe to the pump Cover.

5.1 Preparation for installation

5.1.1 Check environmental conditions

Ensure the necessary environmental conditions (→ 9.2.1 Environmental conditions, page 36)

5.1.2 Preparation of installation site

Ensure that the installation site meets the following conditions:

– There is no foreign matter around the pump

– Enough space is available for installing and removing pipes, as well as for maintenance and repair Work, especially disassembly and assembly of pump and motor

– No external vibration affecting the pump (bearing damage)

– Anti freezing measures Use foundation installation

instructions

Excessive base tension will cause property damage! Place the base on the foundation as shown below.

5.2.1 Place the pump set on the foundation Auxiliary tools, tools and materials:

– Anchor bolt (→ installation drawing)

– Steel gasket

– Mortar filler, no shrinkage

– Level

1. Lift the pump set (→ 4.1 Transportation, 14 pages)

2. Hook the anchor bolt from the bottom to the fixing hole on the surface. Pay attention to the manufacturer's instructions when using adhesive anchors.

3. Place the pump set on the foundation. At the same time, lower the foundation bolt to the prepared ground In the foot bolt hole.

4. Install the pump according to the height and system size with steel accessories according to the following instructions Group:

– Each foundation bolt (1) is equipped with a steel attachment (2) on the left and right sides.

– If the spacing of anchor bolt holes exceeds 750 mm An additional steel attachment (3) is provided in the center of the.

5. Ensure that the base and steel gasket are placed smoothly.

6. Use the machine level to check the allowable height deviation from the longitudinal and transverse directions (1 mm/m)。

7. Repeat the operation until the base is correctly aligned.
