An oversized bracket and seal chamber allows the use of numerous sealing technologies, including packing, mechanical seals and lip seals. The large cast-iron bearing housing allows the mechanical seals to be removed without the need to take the gear pump out of service.
Available on G Series G2-55 - 222 cast iron models, jacketed pump components efficiently heat the seal area and pump internals to maintain process temperature and integrity during operation. Jackets allows for greater temperature control and stability, preventing the product from hardening and damaging the seal upon startup and provides faster startup than a cold pump would allow.
