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"Gp.jpg (12294 bytes)
