A Series General Purpose Pumps

Roper A Series General Purpose Pumps

Pumps from the Roper A Series can be used for a variety of clean fluid pumping applications, including pressure lubrication, hydraulic service, fuel delivery, and general liquid transfer. These pumps provide options for foot or range mounting and are made to run at typical motor speeds.

The fluid being pushed lubricates the interior bearings. The pumps operate silently because there are only two moving parts. They are produced and put together with precise tolerances, and their dependability is periodically verified. Most can be reassembled for operation with comparable efficiency in a counter-clockwise rotation, despite being factory constructed for clockwise rotation (facing the pump drive shaft end).

MECHANICAL SEAL (STANDARD)

Mechanical seals are for those applications where product
leakage is unacceptable. The mechanical seal uses less power
than the packed box and, under proper conditions, has a
longer service life. It does not require adjustment. Our standard
mechanical seal is an elastomeric bellows type seal, with a
temperature limit of 212ºF (100ºC). Special fi tting is available
for higher temperature applications.

MECHANICAL SEAL (POSITIVE DRIVEN)

These are positive driven seals with a PTFE wedge, for use
where corrosive and/or viscous liquids are being processed.
Wedge construction of the secondary sealing element virtually
eliminates leakage. These seals have a temperature limit
of 450°F (232°C). Special fi tting is available for higher
temperature applications.
