Pump for waste solvents / slightly viscous media / self-priming /
EX
Pump for waste solvents in cement plant A major cement manufacturer
uses high-energy fuels in its kilns. The fuels are delivered by
tanker truck. To transfer the fuels, the cement manufacturer
required a pump with EX Zone 1, T3 certification. The pump had to
be insensitive to solids, able to pump slightly viscous media,
self-priming and resistant to solvents. One further prerequisite
for this application was a compact, space-saving design of the pump
and the drive.
As a solution the manufacturer selected a Accuvon AP 100 Rotary
Lobe Pump with bevel gear reducer and motor. Working closely with
the customer, the pump was designed to meet the tough requirements
established by the cement manufacturer.
