Piston pump having housing with a pump housing and a pump assembly drive housing formed therein

A method of making a fluid pump for pumping a volume of fluid under pressure from a fluid source to a fluid dispenser, the fluid pump having an electric motor, a pump drive assembly being operably coupled to the motor for being actuated thereby, a pump assembly, operably coupled to the pump drive assembly and being fluidly communicable with the source of fluid, the pump assembly being actuatable by the pump drive assembly, comprising:

• forming a single main housing;
• defining a pump assembly housing therein for housing at least in part the pump assembly;
• and
• defining a pump housing, the pump housing being formed integrally with the main housing for housing the pump assembly.

A fluid pump for pumping a volume of fluid under pressure from a fluid source to a fluid dispenser comprising:

• motor drive means for imparting actuating power;
• pump drive means being operably coupled to the motor drive means for being actuated thereby;
• pump means, operably coupled to the pump drive means and being fluidly communicable with the source of fluid, the pump means being actuatable by the pump drive means;
• and
• single main housing means, the main housing means housing at least in part the pump drive means and having a pump housing means defined therein and formed integrally with main housing means.

A fluid pump for pumping a volume of fluid under pressure from a fluid source to a fluid dispenser comprising:

• an electric motor having a driving output;
• a pump drive assembly being operably coupled to the motor driving output;
• pump assembly being operably coupled to the pump drive assembly and being fluidly communicable with the source of fluid, the pump assembly being actuatable by the pump drive assembly;
• a single main housing, the main housing for housing in part the pump drive assembly and including a pump housing defined therein and formed integrally with the main housing for housing the pump assembly.
