Hand pump. Animation of a suction hand pump. On the up stroke of the piston the foot valve opens and suction brings water into the pump head. On the following down stroke of the piston the valve on the piston opens up and allows water to flow above the piston. On the successive up stroke of the piston water is pushed out of the outlet.
Comparison of pumps. This article lists different types of pump and provides a comparison of certain key design features. Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface ...
The India Mark II is a human-powered pump designed to lift water from a depth of 50–80 m. [ 1] The Mark II is world's most widely used water handpump. [ 2] The pump was designed in the 1970s to serve village water needs in developing countries and rural areas. The pump is installed on top of a drilled well or borehole and lifts water from the ...
Peristaltic pump in motion. A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
Hydraulic jumps in rectangular channels. Hydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a ...
The simplest example is the bicycle pump, which is used ubiquitously to inflate bicycle tires and various types of sporting balls. [1] Power-operated deep well reciprocating pump; By mechanism. Single-acting reciprocating pump consists of a piston of which only one side engages the fluid being displaced. [2] The simplest example would be a syringe.
Maintenance free pump system without rubber seals in the cylinder. The BluePump design is owned and hosted by the FairWater Foundation who supervises the production and monitoring the performance in the field. FairWater has an active R&D program to update and improve the design whenever needed. Riser Main: 65mm: 65mm: ID70/OD80mm Max Depth ...
The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
