A waste liquid treatment apparatus, a method, and a sample analyzer are provided. The waste liquid treatment apparatus is used for treating waste liquids in waste liquid pipes, and includes at least two waste liquid chambers, a pressure supply device, and a control device. Each waste liquid chamber communicates with at least one waste liquid pipe, and is used for collecting the waste liquid in the waste liquid pipe connected thereto when the inside of the waste liquid treatment chamber is in a negative pressure state. The pressure supply device is connected to each waste liquid chamber, and the control device is configured for controlling the pressure supply device to supply air pressure to each waste liquid chamber, so that the inside of at least one waste liquid chamber is in a negative pressure state at any time during waste liquid treatment, thereby effectively shortening a waste liquid treatment cycle.

A static bilge pump has a body surrounded by a shell, forming a motive plenum therebetween. Inlets in the front of the shell allow a motive fluid to enter the motive plenum. The motive plenum tapers, decreasing in cross-sectional area along with width as it moves toward its aft, and ends at a motive nozzle. The body houses a suction chamber in fluid communication with a suction inlet that is in fluid communication with the bilge of a boat. Ejectors are positioned proximal to and between the motive nozzle and the discharge outlet. When the static bilge pump is exposed to fluid flow from its front to its stern, such as when a boat is in motion, water enters the motive inlets, filling the motive Plenum and acting as a motive fluid. The motive fluid is ejected at high pressure from the motive nozzle, creating suction at the ejectors and discharging the motive fluid as well as liquid with in the suction chamber out the discharge outlet.

A reciprocating piston motor, motor-pump assembly and method for driving a pump. The piston motor includes a pressure medium housing, comprising a first pressure medium chamber having a first pressure medium piston, a second pressure medium chamber having a second pressure medium piston, and a pressure medium control system. The pressure medium control system includes a pressure medium inlet and outlet that are operatively connected to the pressure medium housing. The pressure medium control system is configured to move the pressure medium pistons. A coupling system is provided that is configured to combine the driving forces generated by the first and second pressure medium pistons for driving a fluid pump.

A method of pumping a heat transfer fluid in a thermal energy storage system comprising a first thermal energy storage tank connected to a second thermal energy storage tank via a bi-directional flow member. The first and second thermal energy storage tanks are associated with a pressure vessel system comprising a first and second pressure vessel each pressure vessel being partially fillable with an actuating liquid, wherein, the method for pumping comprises: displacing the actuating liquid from the first pressure vessel to the second pressure vessel, thereby creating a pressure difference in the first thermal energy storage tank with respect to the second thermal energy storage tank, and therein displacing the heat transfer fluid via the bi-directional flow member.
