Pumps intended for specialized purposes must be able to handle a wide variety of chemicals and consistencies. Progressive cavity and peristaltic pumps offer a solution by providing the high power you require while managing delicate materials.
There are various online and offline marketplaces to find progressive cavity and peristaltic hose pumps for sale. Let’s compare these two pumps to know exactly which one you need.
What are Peristaltic Pumps?
Positive displacement pumps or peristaltic pumps are kind of positive displacement pumps. The layout of the pumps is based on the concept of peristalsis.
In a scientific sense, peristalsis is a sequence of muscular contractions that transfers food from one area of the gastrointestinal tract to another.
How Does A Peristaltic Pump Work?
An engine, gearbox, hose, and either shoes or rollers are included in each unit. They work by compressing a single component called the “hose” or the tube with rolls or shoes to produce a routine process of suction, flow, and pressure.
The pumps are classified as a “non-clog” pump since it doesn’t have any valves. Peristaltic pumps are self-priming and can produce vacuum lifts of up to 8 meters from dry while also handling air.
Because a peristaltic pump’s rotational motion is sluggish, a gearbox reduces the motor speed down as low as “1rpm” inside the pump head.
Peristaltic Pumps Can Be Utilized in a Variety of Situations
Peristaltic pumps are utilized in various sectors because they handle everything from clear low viscous liquids to sludges and mixtures, including abrasive particles like pebbles, cuts, and metal particles.
They can manage viscosities ranging from “1cst to 55,000cst”, making them suitable for a wide range of fluids. Most applications need a low to moderate flow (36,000 L/hour) at moderate to high pressure (15-bar). Nowadays, it’s easy to find high-quality peristaltic hose pumps for sale through online stores.
Applications of Peristaltic Pump
They may be used for groundwater levels testing, gearbox refilling, biochemical transfer, and rodent perfusion, which involves passing a substance such as formaldehyde into a mouse’s bloodstream to preserve organs and tissues.
Peristaltic pumps are sometimes utilized in labs because they can carry fluids without altering their composition or harming cell growth. Still, they’re also utilized in the food sector for machinery filling. At reduced pressure, they can function at 1Hz, compensating for the tiniest amounts.
They’re particularly well-suited for fluids, such as Sodium Hypochlorite, since they don’t have any valves or seals that may open as pressure rises, like diaphragmatic pumps, enabling spillage. Vapor trapping may occur when centrifugal pumps are utilized with gaseous fluids.
What Is a Progressive Cavity Pump?
A progressive cavity pump refers to a positive displacement pump intended to handle high viscosity fluids and difficult pumping applications. While it’s a flexible pump that can perform a wide range of tasks, it’s especially well-suited to metering liquids and circulating thick or shear-sensitive substances.
Progressive cavity pumps are also known as “progressive cavity pumps”, “PC pumps”, “cavity pumps”, or “prog cavity pumps”.
How Do Progressive Cavity Pumps Work?
A positive displacement concept is used in a progressive cavity (PC) pump. A suction intake flows into an extended shell of a conventional computer. A helix ‘worm’ rotor and stator assembly are placed inside this housing.
The “rotor helix” is offset from the stator, resulting in cavity gaps in the unit that are filled with temporary seals when the rotor makes contact with the stator’s surface. The cavities develop when the rotor starts to spin eccentrically, drawing in the product as it is ‘progressed’ through the assembly, and the product is ejected via the discharge port.
Top Applications of Progressive Cavity Pumps
PCPs are suitable for fluid pouring applications that demand great precision and tiny quantities in electronics. This special ability of PC Pumps has put it in high demand, and that’s why many professionals try to find the best progressive cavity pumps for sale.
PCPs enable improved consistency, effectiveness, and performance in a variety of industries, including MEMs and automotive, by dispensing exact quantities of:
- Solder Paste
- Conductive Epoxy
- Bonding Materials and more
There are several online marketplaces where you can find the best progressive cavity pumps for sale for all your needs.
