Unpacking, Handling, and Storage

Step 1

Refer to the pump weights guide before selecting and using any lifting gear. The drawings show how the pump should be lifted. Ensure that lifting equipment is correctly rated and used within these limits.

Step 2

On receipt always:

 – Check the delivery note against the goods received.

– If motorized, check that the drive instructions are available.

– Be careful not to discard any manuals that may be enclosed with the packaging.

 – Inspect the packing for signs of damage in transit.

– Carefully remove the packing away from the pump.

– Inspect the pump for any visible signs of damage.

– Clean away the packing from the pump port connections.

– Report any damage immediately to the carrier.

Step 3

After receipt and inspection, if the pump is not to be installed immediately, the pump should be repacked and placed in suitable storage. The following points should be noted:

 – Plastic or gasket type port covers should be left in place.

– Pumps received wrapped with corrosion-inhibiting treatment material should have wrapping replaced.

– A clean, dry storage location free from vibration should be selected. If a moist or dusty atmosphere is used for storage, further protect the pump or unit with a suitable cover.

– Rotate the pump/pump unit by hand weekly, to prevent bearing damage.

– All associated ancillary equipment should be treated similarly.

The CZECH TECH LOBE PUMP range of pumps is of conventional rotary lobe pump design with the positive displacement being provided by non-contacting, contra-rotating tri-lobe rotors within a fully swept pump chamber.

The LOBE PUMP range has a universal gearbox design which gives the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane by changing the foot position.

Handling from low to high viscosity pumped media, the pump’s characteristic smooth, low shear pumping action is ideal in application areas such as Brewing, Dairy, Food industries, and is suitable for CIP (Cleaning In Place).

Pump duty conditions:

 The pump should only be used for the duty for which it has been specified. The operating pressure, speed, and temperature limits have been selected at the time of order and MUST NOT be exceeded. These details are stated on the original order documentation and if not available may be obtained from your supplier quoting pump model and serial number.

The direction of flow: The direction of flow is dictated by the direction of rotation of the drive shaft. Reversing the direction of rotation will reverse the flow direction.

Pump Lubrication:

 The pump will be supplied filled with grease. It is recommended to change the grease every 5000 hours of pump operation. When changing the grease one of the recommended greases listed below must be used:

Aralube MFL 00

BP Energrease PR-EP00

Mobilux EP 004

Cleaning in place (CIP)

The pump can be manually cleaned or cleaned in place (CIP). The following is an example of a typical CIP procedure. However specific advice for each application should be sought from the pump supplier.

Typical CIP procedure

1. Flush through the system with cold water or bore water (6°C) (43°F).
2. Run hot caustic soda (70-80°C) (158-176°F) at 2.5% dilution through the system for 20-30 minutes. 3. Final flush through with cold water again.

Warnings – Never touch the pump or the pipelines as they can be extremely hot! – Do not subject the pump to rapid temperature changes during CIP procedures, as pump seizure can result from thermal shock. A suitable bypass is recommended. – Always rinse well with clean water after using a cleaning agent. – Always use rubber gloves and protective goggles when handling caustic agents. – Always store/discharge cleaning agents in accordance with current rules/directives.

Dismantling Step 1 Before disassembling the pump refers to safety precautions. See exploded view drawings. Removing rotor case cover 1. Remove the rotor case cover screws and cover.
Step 2 Removing rotors 1. Insert a plastic/wooden block between the two rotors to stop them from turning. 2. Remove rotor nuts, rotor nut O-rings, and rotors. 3. Remove the rotor case cover O-ring and spline sealing O-rings if these are to be replaced.
Step 3 Removing primary seal components Primary seals removal and fitting for seal removal.
Step 4 Removing rotor case 1. Remove the rotor case retention screws. 2. Tap both sides of the rotor case with a soft hammer. 3. Take care not to allow the rotor case to drop onto the shafts during the removal process.
Step 5 Removing canister 1. Place a tray under the canister to collect the waste lubricant. 2. Remove the four canister retaining screws and allow lubricant to drain. 3. Remove the canister from the bearing housing which is sealed with an O-ring. To assist in removal a suitable lever can be used in the slots provided. 4. Remove the canister O-ring if this needs to be replaced.
Step 6 Canister lip seal removal Extract the lip seal from the seal retainer. It is essential to renew the lip seal prior to assembly.
Step 7 Removing timing gears 1. Loosen the bearing nuts with a ‘C’ spanner by tapping sharply. 2. Remove the torque locking assembly screws in several stages (do not fully undo each screw on the first stage of screw removal). 3. Insert the screws into the threaded holes in the assembly flange and gradually tighten in a crossed sequence until the back cone is released. 4. Slide timing gears off the shafts .
Step 8 Shaft assembly removal 1. Remove bearing nuts with a ‘sharp tap’ on a ‘C’ spanner (see also drawing shown in step 7). 2. Using a soft hammer gently tap the rear end of each shaft to remove through the front of the bearing housing, supporting each shaft during removal. As the shaft is removed the bearing housing lip seal and rear bearing will also be removed. 3. Remove lip seal from shaft. It is essential to renew the lip seal prior to assembly.
Step 9 Bearing removal 1. Mount the shaft vertically in a press (rotor part of the shaft down) with a tool positively located against the front bearing inner ring with rolling elements as shown, and apply pressure to the top of the shaft so that the shaft moves through the bearings. 2. From bearing housing tap the outer bearing rings (front and back) and remove shims. Renew bearings if removed from the shafts for any reason.
