Lowara CA Series Twin-Turbine Centrifugal Electric Pumps

Power and Hygiene: The Evolution of the Centrifugal Pump

Problem: You've installed a standard pump, but the shower pressure upstairs is weak, or the garden sprinklers don't turn up all the way. This happens because the pump has a good flow rate but not enough "head."

Solution: The Lowara CA Series solves the problem by adding a second compression stage. The water passes from the first to the second impeller, gaining speed and energy. Furthermore, unlike cast iron pumps that rust, the stainless steel construction ensures consistently clean, potable water.

Decoding Lowara CA Codes

Choosing the right model is simple if you know how to read the acronym (e.g. CAM 70/33 ):

• ✅ CAM: The "M" at the end indicates that it is single-phase (220V) for household use. If it is only "AC", it is three-phase.
• ✅ 70: Indicates the optimal nominal flow rate. Models range from 70 to 200 (the higher the number, the more water it displaces).
• ✅ 33 or 34: Indicates the head (motor power). A higher number (e.g., /43 or /45) means the pump is more powerful and pushes higher.

Frequently Asked Questions about Lowara CA Series

1. What is the difference between CA (Twin-turbine) and CEA (Single-impeller)?

The CEA has a single impeller: it moves a lot of water but at medium pressure. The CA has two impellers: with the same motor, it generates much higher pressure . Choose CEA for quick transfers or fillings. Choose CA for domestic pressure tanks, sprinkler irrigation, and systems where "force" is needed in the water.

2. Are these pumps suitable for hot water?

The standard version with EPDM gaskets resists temperatures up to 85°C , making it ideal for use in residential or light industrial heating systems. For higher temperatures (up to 110°C), the version with FPM (Viton) gaskets must be requested.

3. Are the fittings threaded or flanged?

Most CA series pumps for residential use have gas (RP) threaded suction and delivery ports, which are easy to connect to standard pipes. However, some larger or specialized models may have counterflanges. Always check the technical drawing in the product sheet or ask us for assistance.
