curves ensure minimal flow variations
when fluctuations in delivery head occur.
This helps to ensure that the pumps pass
forward the required flow consistently
and reliably. High pump efficiencies with
non-overloading power curves, only draw

delivering optimum use of energy.
An adjustable suction liner is an
optional feature that carries the
benefit of allowing easy restoration of
pump performance after wear to the
hydraulic end. This delivers immediate
energy savings through simple site
adjustment of external screws on the
pump casing to restore efficiency. This
ensures sustainable pump performance
and efficiency are both practical and
easily achievable as part of a routine
maintenance inspection. The energy
savings through restoring efficiency
can more than cover the cost of the site
maintenance activity.
