VERTICAL SUMP PUMPS

The range of vertical sump pumps includes:

  • Type BA: Cantilevered shaft with single bearing support, suitable up to 32NB.
  • Type BT: Cantilevered shaft with double bearing support. This pump is suitable for flows over 400m3/h and discharge pressure up to 1000kPa. Depth normally around 1200mm.

In all cases the pumps are designed in such a manner that no metal parts will be in contact with the liquid. The pumps are thus ideally suited to corrosive duties.

The cantilevered pumps are particularly suitable for liquids containing solids, as they have no seals or supports, which could

wear down in time. The cantilevered pumps also have reasonable NPSH values, so that suction pipes can be installed.

The Tecnium range of sump pumps are not only being used in chemical sumps, but also as process pumps in tanks where the installation of a submerged pump improves operating conditions as well as overall safety of the plant.

TECNIUM VERTICAL PLASTIC PUMPS (SEAL-LESS)

The BVS range of vertical pumps offers special advantage for the process design engineer as well as the maintenance team:

  • The pump has no mechanical seal.
  • Due to the absence of a shaft seal there is no area where friction can  cause problems during operation of the pump.
  • The pump can thus run dry for as long as necessary.

The absence of the seal is obtained through the use of a specially designed back-impeller, which reduces the amount of liquid that passes the back-end of the pump.

The small amount of liquid that passes the back-end is collected in a chamber and is returned by gravity to the container from where the pump is pumping. To allow the .

liquid to be returned, the pump has to be installed at the maximum liquid level in the tank.

Various installation arrangements are possible, depending on the process conditions existing. Please ask for advice in this regard.

The BX range of pump is available for smaller pumps up to flow rates over 200m3/h and 1 000kPa discharge pressure.
