In the most demanding jobs where the torque, viscosity, pressures and abrasion resistance are exponentially high our gear joint style 70400 series is the perfect fit. The 70400 series pump is designed and built for applications where joint life is critical. The crowned gear joint design is sealed from the liquid; providing a drive system with a greater wear area and lower stresses making it the superior design in joint technology. Its construction makes this gear joint pump ideal for applications where a longer maintenance interval is desired, accessibility to the pump is limited or where downtime must be kept to a minimum. Also, because the 70400 series gear joint pump comes standard with large clean-out ports, large objects can be removed from the suction housing without dismantling the pump.
