The Lowara Ecocirc N circulation pumps are designed for water circulation in domestic hot water… High efficiency pumps with ECM-technology and permanent magnet rotor.
What is a vertical multistage pump?
A vertical multistage pump is a centrifugal pump containing two or more impellers. The fluid flows into the inlet of the pump casing where it flows into the eye of the impeller. The impeller is driven & rotated by mechanical means such as an electric motor or engine etc.
Who makes Lowara pumps?

What are multi stage pumps?
Multistage pumps are defined as pumps in which the fluid flows through several impellers fitted in series. This type of pump is often used in power station applications, e.g. as a boiler feed pump and in industrial applications requiring high pressures.
Where are Lowara pumps made?
Italy
Lowara is an Italian company that was established in Montecchio Maggiore, Vicenza in 1968. They have two manufacturing facilities in Italy with a staff of 800 utilising 45,000 square metres of facility space.
What are vertical multistage pumps used for?
What are Vertical Multistage Pumps? Vertical Multistage Pumps are used commonly when liquids need to be transferred with high pressure. This is accomplished by the pump having multiple impellers in which the fluid flows through.
Why vertical pumps are used?
Pros of Vertical Centrifugal Pumps Smaller footprint when compared with horizontal pumps. Suitable for applications that have restricted surface area. The NPSH can be altered thereby making it suitable for a wide range of applications. Suitable for liquids with high pressures and high temperatures.
How does a multi stage vertical pump work?
How does a multi stage pump work? A multistage pump operates by one impeller feeding into the next impeller and the number of impellers required depend on the discharge pressure requirement. Liquid enters the pump and then passes through the various number of impellers in a sequence from the left to right.
Why are multi stage pumps used?
Multistage pumps use multiple impellers plus diffusing element stages for developing higher head through the series addition of head from one stage to the next. These pumps are typically used in applications for boiler feed, reverse osmosis, and other high pressure and temperature applications.
How does a vertical multi stage pump work?
When would you use a multistage pump?
The horizontal configuration of multistage pumps is best applied in applications like these:
- Reverse Osmosis.
- Boiler Feed.
- Shower.
- Spray.
- Cogeneration.
- Pressure Boosting.
- High Pressure Cleaning.
- Snow making.
Is vertical or horizontal pump better?
On the positive side, horizontal centrifugal pumps are easier to install and maintain with internal parts that are simple to access. In general, the working temperature and pressure are lower in horizontal pumps when compared to vertical alternatives.
