An Introduction to PMV Pump Progressive Cavity Pumps
In most industries, fluid handling is one of the most important concerns. To carry out this process a company must have the correct equipment. There are a number of options depending on the application, but reliability, quality and performance will always be required for an efficient process. One option, which is widely used for industrial fluid handling applications, is the progressive cavity pump. These pumps are also referred to as “PC” pumps. There are a number of progressive cavity pump manufacturers in the China, but PMV Pump differentiates itself by not only delivering high quality, reliable products, but also catering to its clients on a more personal level.
What are Progressive Cavity Pumps?
Progressive cavity pumps are self-priming, positive displacement pumps. They consist of two elements: the rotating eccentric screw and the stationary stator. The rotor conveys the medium with low pulsation and vibration through the stator. The flow rate is proportional to the speed of rotation, so increasing the speed will increase the flow. Additionally, increasing the number of stages (rotor pitches) raises the pump pressure proportionally. The design allows pumping in both directions, a high suction lift, and low shear conveying.

How do Progressive Cavity Pumps Work?
The working of these pumps is very easy to understand.
- As the rotor rotates, it forms a tight seal against the flexible rubber. This forms cavities, which are sealed tightly.
- These cavities then carry the liquid or fluid towards the discharge port.
- Since the cavities between stator and rotor are tightly sealed, the pumped liquid does not change its size or shape (low shear).
- The overall design of these pumps, helps the fluid to move at a very steady rate.
- Liquid plays the role of a lubricant between the pumping elements.

What Models of Progressive Cavity Pumps does PMV Pump offer?
The following three brands of the progressive cavity pumps:
1. Bornemann® Equivalent EH Pumps (PMV Pump):
The Bornemann® equivalent EH pumps are among the most popular types of pumps, owing to their excellent reliability, versatility, and performance. PMV Pump also offers Bornemann® equivalent EL and ER models.
2. Netzsch® Equivalent Pumps: These pumps are economical, and provide a cost-effective solution in a variety of applications.
3. Moyno® Equivalent Pumps: The Moyno® equivalent pumpsare ideal for use in applications, such as limestone slurries, wastewater treatment, polymers, etc. PMV Pump provides equivalent pumps to the Moyno® 34401 wobble rotor pump and 2000 series pumps.

Sanitary Screw Pumps
What is the function of sanitary pump?
A Centrifugal Sanitary Pump is a machine used to transfer quantities of fluids from one place to another. These machines apply kinetic energy stored in the motor to move the liquids. The main function of these pumps is to move the product and cause the liquid to flow at a desired speed and force.
What is a sanitary lift pump?
What is a Lift Station? A wastewater lift station is a pumping station that moves wastewater from a lower elevation to a higher elevation. The benefit of using a lift station in a sewage collection system is that it saves a substantial amount of money in excavation costs, which involves digging for sewer pipes.
Hopper Pump
What is a hopper pump?
Open Hopper Pumps are a type Progressive Cavity Pumps. The open hopper pump inlet allows gravity flow of highly viscous media on to the augur-on-coupling rod which pushes the substance to the pumping element.
What is a progressive cavity pump used for?
Progressive cavity pumps are ideal for pumping fluids that have higher viscosities. With a centrifugal pump, the flow rate goes down as the fluid viscosity goes up. This is far less efficient, as the pump must then increase its energy consumption in order to keep up.
