2. Lobe pump - Wikipedia

   en.wikipedia.org/wiki/Lobe_pump

   A lobe pump, or rotary lobe pump, is a type of positive displacement pump. It is similar to a gear pump except the lobes are designed to almost meet, rather than touch and turn each other. An early example of a lobe pump is the Roots Blower , patented in 1860 [ 1 ] to blow combustion air to melt iron in blast furnaces, but now more commonly ...

3. Albany Pumps - Wikipedia

   en.wikipedia.org/wiki/Albany_Pumps

   The original gear pump design has been developed into modern and reliable machines capable of working for up to 100,000 hours on important lubrication duties. As well as Gear pumps, Albany produces Centrifugal Pumps, Lobe, and Twin Screw Pumps (based on Stothert & Pitt Design).

4. Roots blower - Wikipedia

   en.wikipedia.org/wiki/Roots_blower

   Because rotary lobe pumps need to maintain a clearance between the lobes, a single stage Roots blower can pump gas across only a limited pressure differential. If the pump is used beyond its specification, the compression of the gas generates enough heat so that the lobes expand to the point that they jam, damaging the pump.

6. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   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 water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

7. Sundyne - Wikipedia

   en.wikipedia.org/wiki/Sundyne

   HMD Pumps in England invents and engineers the world's first magnet drive pump. 1957—Sundstrand develops the first water injection pump for the commercial jet aircraft industry. The pump is designed to boost engine thrust during takeoff. 1962—Sundstrand develops the first Sundyne high-speed centrifugal pump and sells it to Shell Chemical.
