Vacuum pump

A vacuum pump that is connectable to an external system and configured to evacuate material from the external system, the vacuum pump comprising:

• a housing including a motor housing, a pump housing, and a trestle that separates the motor housing and the pump housing;
• a base coupled to a lower portion of the housing;
• a motor assembly that is positioned within the motor housing;
• a control panel disposed on a first sidewall of the housing;
• a battery that is coupled to the motor housing and configured to supply electrical current to the motor assembly;
• a pump assembly that is positioned within the pump housing, the pump housing is sealed relative to the motor housing to form a compression chamber storing a lubrication fluid, wherein the pump assembly is driven by the motor assembly and is in fluid communication with the compression chamber;
• an inlet manifold coupled to the trestle and configured to fluidly connect the pump assembly to the external system;
• and
• a bumper composed of an elastomeric material and coupled to the trestle on a second sidewall of the housing that is opposite the first sidewall, the bumper is configured to protect the vacuum pump from damage when inadvertently dropped, and wherein the first sidewall and the second sidewall extend upward from the base.
