GP Series pumps provide reliable
service for high volume transfer or re-circulation of corrosive liquids. The thermoplastic
resins use a fill material of glass or carbon for additional strength and wear resistance.
Mechanical seal options allow for difficult solution applications – these types of
options are not normally available with thermoplastic pumps. The pump can be supplied
direct mounted to a TEFC motor – Motor options included "Chem Duty" and
"Explosion Proof"
