Abstract
A high pressure pump includes a pump housing. A piston rod located within the pump housing defines a plurality of pump cavities and a plurality of piston cavities. Movement of the piston within the piston cylinder pumps the fluid from the piston cavities out of the high pressure pump. The continuous pumping of HWBF from the pump housing provides fluid at a relatively constant flow and pressure. The HWBF pressure is also at a higher pressure than traditional single stage high pressure pumps can provide.
