Standard Refrigeration Pump

REFRIGERANT EMISSION FREE™
SEALING TECHNOLOGY

An ultra-reliable system consisting of two
mechanical seals mounted back to back
Inboard seal prevents escape of refrigerant from
the pump casing
Outboard seal acts as a fail-safe or backup, and
provides containment of a system compatible
barrier fluid.
NPSHR
Exceptional NPSHR characteristics
Characteristics are enhanced throughout entire
operating range due to the single stage impeller
and four pole operating speed
Vapor Entrainment
Seals are oil lubricated, and do not rely on the
presence of pumpage for lubrication or cooling
The double mechanical sealing system allows
the pump to continue to run until the system
stabilizes and the pump re-primes itself –
nuisance-tripping is avoided.
