Thread connections reduce pump sizes

Manufacturers of polyelectrolyte dosing systems are benefiting from developments in Jabsco's bronze flexible impeller pumps (FIPs).

Manufacturers of polyelectrolyte dosing systems are benefiting from developments in Jabsco's bronze flexible impeller pumps (FIPs).

Polyelectrolyte mixtures are used in treatment of sewage and sludge or for the treatment of potable and process water for the removal of colloidal solid matter from liquids.

Jabsco FIPs are widely used to transfer concentrated, wetted polyelectrolyte to a maturation tank for aging before use.

Latest versions of the Jabsco pumps now being specified use thread connections in place of bolt-on pipe fittings.

This reduces the size of the pump making it easier and more economical to install, especially in confined spaces.

Interestingly, the Flexible Impeller principle was originally adopted because its installation dimensions were already much smaller than the progressive cavity pump type previously used.

The bronze pump head is powered by a 1.5 kW, 3-phase electric motor in this flooded suction type application.

The high concentration of long-chain-molecular polyelectrolyte mix is particularly susceptible to damage during transfer.

The extremely gentle pumping action of the Jabsco flexible impeller principle combined with low 1000 rpm running speed has proved perfect for this demanding application over many years.

Jabsco flexible impeller pumps are also available with bodies in stainless steel, epoxy or phenolic compounds and will deliver flows rates op to 500 litres per minute.
