    en.wikipedia.org/wiki/Circulator_pump

    A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.

  3. Reciprocating pump - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_pump

    Reciprocating pump has wide application and to clear the basic idea it is necessary to know the basic parts. The basic parts along with its function; Water reservoir - it is not a part of reciprocating pump, however, it is the main source where from the reciprocating pump takes the water. It may be a source of other fluid as well.

  5. Liquid-ring pump - Wikipedia

    en.wikipedia.org/wiki/Liquid-ring_pump

    Single-stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 47 millibars (4.7 kPa), and two-stage pumps can produce vacuum to 25 torr, assuming air is being pumped and the ring-liquid is water at 15 °C (59 °F) or less. Dry air and 15 °C sealant-water temperature is the standard performance basis, which most manufacturers use for ...

  6. Protein skimmer - Wikipedia

    en.wikipedia.org/wiki/Protein_skimmer

    The recirculating pump pulls water out of the skimmer and injects air to generate the foam or air–water mix before returning it to the skimmer reaction chamber—thus 'recirculating' it. The feed pump in a recirculating design typically injects a smaller amount of dirty water than co/counter-current designs. The separate feed pump allows easy ...

    en.wikipedia.org/wiki/Water_timer

    The solenoid/diaphragm timer uses more battery power throughout the "on" cycle because the solenoid must be actuated the entire time that the water flow is "on". The ball valve timer using the motor and gear actuator only uses more battery power during the few seconds that motor is used to turn the water flow on or off.

    A highly anticipated rookie WR class hasn't fully lived up to the hype, while a couple of running backs have risen up and a loaded class off offensive and defensive linemen have delivered.

  9. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    Feedwater pumps range in size up to many kilowatts and the electric motor is usually separated from the pump body by some form of mechanical coupling. Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam ...
