Page 3: Product Description
3. Product description As standard, the booster systems consist of two to four pumps coupled in parallel and mounted on a common base frame with all the necessary fittings and a control cabinet. Fig. 3 Front view of Hydro Multi-B CR booster system Fig. -
Page 4: Application Types
4. Application types The booster systems are available for the following application types: • constant-pressure boosting • tank filling. Furthermore, two control variants of the booster systems are available. The control variants are described below. 4.1 Booster system for constant-pressure applications The booster system for constant-pressure applications is designed to maintain a constant pressure on the discharge side of the pumps. -
