HOW EFFICIENT IS YOUR WASTEWATER PUMP?

In selecting the most efficient wastewater pump, do you always choose the pump with the best hydraulic efficiency?

If so, you may not be winning the pump efficiency “game,” according to Hydro Innovations.

If selecting a clean water pump, energy costs amount to up to 80-90% of a pump’s overall life cycle cost.

For a wastewater pump, energy costs may only equate to 25%-35% of a pump’s whole of life cost, with blockages, downtime, ease (or otherwise) of maintenance, reliability, and cost of repairs being the biggest cost.

A pump can be very hydraulically efficient, but if it is not an efficient solids handler, all the costs will be in maintenance and upkeep of the pump.

Factors such as blocking frequency, un-blocking efficiency and ease of access should be taken into account.

Also, if the internal clearances of a pump are easily adjusted, that pump will maintain its hydraulic efficiency and also block less frequently than a pump whose clearances have “opened up” because of the abrasive action of wastewater.

Downtime is another “killer” and a hidden cost of a poorly selected wastewater pump. Some unreliable pumps can cause frequent overflows and production line stoppages, and if they are difficult or time consuming to repair, make the problem worse.

A pump that is a good at passing solids (including stringy materials such as rags and gloves) will be more reliable.

And if it can be put back into service quickly after a breakdown, will be an asset worth having.
