What is the stator on a pump?

What is the stator on a pump?

Stators are metal tubes with internally molded cavities of synthetic or natural rubber. The rotor seals tightly against the flexible rubber inside the stator as it rotates, forming tightly sealed cavities which carry the liquid toward the discharge port.

How does a Mono pump work?

Progressive cavity pumps, otherwise referred to as a helical rotor pump, eccentric screw pump or mono pump, are part of the positive displacement family. Positive displacement pumps are characterised by an operation that moves fluid by trapping a fixed volume and forcing that trapped fluid into the discharge pipe.

How does a progressive cavity pump work?

A progressing cavity pump is a positive displacement pump employing a rotor and stator assembly to create temporary chambers to draw fluid into, which ‘progress’ through the pump resulting in the fluid being expelled through the discharge port.

What does a stator do?

The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.

What is pump rotor?

Helical Rotor Pumps The rotor is fitted inside the stator which is lined with rubber. The rotor rotating inside the stator forms cavities via which media is pumped from suction to the discharge end of the pump. The rate of flow of the liquid is usually inversely proportionate to the pressure.

What is pump cavitation?

Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). When cavitation takes place, air bubbles are created at low pressure.

What is pump slip?

What is Pump Slip? Slip is the loss of pumping capacity due to fluid leaking back through a pump from the discharge side to the inlet side. It can affect the efficiency of all types of pumps although the actual causes may be very different.

What is the purpose of a progressive cavity pump?

A progressive cavity pump is used when the pumping application is not suited to a centrifugal pump. One of the clearest examples of when to use a progressive cavity pump is when the liquid has a higher viscosity, or thickness, than water.

Will a bad stator drain a battery?

As far as the battery, yes a bad stator/regulator can destroy a new battery. If it’s run at a very low voltage without being recharged then it can be destroyed. It actually happens all the time. In most cases if we replace a stator or regulator the battery has to be changed as well as it won’t hold a charge.

What kind of pump is a rotor stator?

Rotor Stator pumps are progressive cavity pumps, which are a type of positive displacement pump. Some also call them eccentric screw pumps. Just as there are many names for them, there are also many different areas of use for rotor stators. Our customers mainly use them for pumping grout, screed, mortar, plaster or refractory tundish.

Which is the heart of a Mono pump?

The heart of the Mono pump is the rotor and stator. As the single helix rotor revolves eccentrically within the double helix of the stator, a continuous cavity is formed and progresses towards the discharge end of the pump as the rotor rotates.

How does a rotary positive displacement pump work?

The rotary positive displacement action of the pump ensures a continuous non-pulsing flow. As the discharge capacity of the pump is constant for a given speed of rotation and pressure, accurate dosing or metering of the product can be achieved Sorry, flash is not available.
