What is a peripheral pump?
A peripheral pump uses a small impeller and peripheral channel to generate relatively high pressure at modest flow rates.
What applications suit peripheral pumps?
They are commonly used for clean-water transfer and pressure applications where high head and comparatively low flow are required.
Can peripheral pumps handle abrasive liquids?
Generally they are intended for clean, non-abrasive liquids. Check the specific pump’s permitted liquid properties before use.
What types of Calpeda pumps can I explore?
Calpeda produces pumps for water supply, pressure boosting, drainage and circulation. Choose a model according to the required flow, head and liquid.
Are Calpeda pumps suitable for commercial installations?
Yes. Calpeda offers pump ranges for domestic, commercial and industrial duties; suitability depends on the individual model and duty point.
How do I choose a replacement Calpeda pump?
