Abstract:
1. A discharge head for high pressure pump applications, comprising: a motor mounting plate configured for mounting on or to a motor; a base plate configured for mounting on or to a pump assembly; an elbow transition mounted on the base plate and configured between the base plate and the motor mounting plate for providing discharge from the pump assembly; a seal housing pipe configured to partially extend from the elbow transition towards the motor mounting plate, to receive a mechanical seal or packing arrangement and to provide 360 degree access to the mechanical seal or packing arrangement; four supporting pipes configured to couple the motor mounting plate and the base plate; four ribs configured to couple the four supporting pipes and the seal housing pipe and to prevent substantially lateral and torsional movement, including movement due to reacting hydraulic forces at a pump nozzle and inertia from a driver; the discharge head being configured to have a base plate area, configured so that the discharge head has a pipe support angle that is around 80° versus 60 to 70° from a known device used for high pressure pump applications; and the discharge head also being configured to have an overall vibration amplitude achieved from a max relative movement of about 0.003″ between the seal housing pipe and the motor mounting plate so as to substantially increase motor stand structure stiffness and maximum nozzle flange pressure ratio.
