PAT – Pump as Turbine
KBL’s Pump as Turbine (PAT) is a unique pumping solution
that can be operated in reverse as a turbine for generating
micro hydroelectricity (up to 100 kW). In a PAT, the turbine is
actually the impeller of a centrifugal pump “running
backward” and the generator is simply the pump’s induction
motor.
Overview
The initial cost of KBL’s PAT solution is almost half the cost of
a conventional hydro turbine of equivalent size. The cost-
efficient PAT pump is primarily used for meeting smaller
energy requirements in industries. The pump facilitates
better returns on investment.
KBL’s Pump as Turbine (PAT) solution installed as a full-
fledged energy generation unit, is not just helping companies
and government projects in reducing their energy costs but is
also being considered as a potent alternative for combating
global warming. The Tansa Dam Project was benefitted with
350,000 units of annual power generation capacity using
KBL’s Pump as Turbine. It is ideal for facilitating supply of
hydropower in manufacturing set-ups, buildings, hotels, etc.
