What type of pump is a Viking Pump?
Viking Pump, a Unit of IDEX Corporation, leads the world in the design and manufacture of rotary Positive Displacement Pumps for use in some of the toughest applications.
What is a Viking pump used for?
Compact and Powerful Pumping Technology Vane pumps are used for liquid transfer applications from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam-shaped cavity.
How does a internal gear pump work?
An internal gear pump moves a fluid by repeatedly enclosing a fixed volume within interlocking gears, transferring it mechanically to deliver a smooth pulse-free flow proportional to the rotational speed of its gears.
What is a gerotor oil pump?
A gerotor is a positive displacement pump. The name gerotor is derived from “generated rotor”. A gerotor unit consists of an inner and outer rotor. Gerotor pumps are generally designed using a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs.
What is the advantages of internal gear pump?
The internal gear pump is non-pulsing, self-priming, and can run dry for short periods. They’re also bi-rotational, meaning that the same pump can be used to load and unload vessels. Because internal gear pumps have only two moving parts, they are reliable, simple to operate, and easy to maintain.
What happens if you run a hydraulic pump backwards?
A common myth is that in reverse rotation, the pump causes backward flow, that is, IN the discharge and OUT the suction. In reality, a pump operating in reverse rotation because of wiring or phase change will pump in the normal direction. Now, it won’t pump very well. Its flow will be reduced, as will its head.
What will happen if gear pump is reversed?
It varies by type and design, but there are several potential consequences: Reduced flow and head… oddly enough, flow is still going in the same direction, it’s just reduced (more on this shortly) Noise.
Which is positive displacement pump?
A positive displacement pump makes a fluid move by trapping a fixed amount of the fluid and forcing (displacing) that trapped volume into a discharge pipe or discharge system. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses.
Can gear pumps run dry?
Centrifugal, rotary vane, and gear pumps should not be run dry; exceptions are if the gear or impeller is made of a self-lubricating material such as RYTON in which case the pump can be run for a few minutes while priming.
