➢
If a hot product is pumped, the pump should not stand still when filled for a longer period
of time. This could cause leakage from the pump.
➢
Below 0°C (32°F) plastic materials become more fragile what can cause accelerated wear of
parts made of these materials. This is a hazard that has to be accepted when pumping such
cold products. Also in such case, when a pump is not operational it should be drained of all
liquid.
➢
Bear in mind that the viscosity of the product changes with temperature. This has to be
taken into consideration when selecting the pump.
➢
The fluid remaining in the connected piping, as well as in the pump itself, may expand
because of freezing or heat, which may cause damage to the pump or/and piping, and lead
to leakage of the fluid.
➢
Some parts of the TE pump can become hot during operation and cause burns, therefore
make sure to use appropriate protection when handling the pump.
1.8.8. Rotating parts
Do not tamper with the protection of the rotating parts, do not touch or approach rotating
parts in movement.
1.9. Example of installation
1. Motor power supply
2. Gate valve
– compressed air
3. Flexible hose
4. Air treatment system
5. Flexible piping
6. Gate valve suction
7. Gate valve discharge
8. Coiled flexible piping
9. Flow gauge
10. Safety valve
1.10. Recommended installations
The Tapflo pump is flexible in the way you are able to install it.
1.10.1. Flooded
The piping system is designed with a positive suction head. This is the best way of installation
where it is necessary to completely evacuate all liquid from the container, or where viscous
(thick) products are transferred.
NOTE! Do not exceed 0,7 bar suction pressure! Higher pressure may cause premature
diaphragm failure and irregular pump operation.
