Horizontal multistage pumps for water pressure applications
Horizontal multistage pumps are horizontal centrifugal pumps used where water pressure, compact installation layout and multi-stage pumping equipment need to be considered together. They are relevant for water boosting pumps, pressure boosting systems, commercial pump units and industrial fluid circulation duties where the pump specification must match the pipework, electrical supply and required pressure level.
A horizontal multistage pump should be selected by checking the product construction, connection type, pressure rating and voltage stated for the model. The product information includes centrifugal and multi-stage centrifugal pump types, with self-priming versions and pressure controller versions on selected DAB EuroInox models.
Construction materials and pump types
Product options include cast iron and stainless steel 304 construction. Cast iron appears on Foras centrifugal pump models, Foras horizontal multi-stage centrifugal pumps and Rovatti horizontal ME models. Stainless steel 304 appears on DAB EuroInox and Foras Plus 3S multi-stage centrifugal pumps.
For buyers comparing industrial horizontal pumps, the material and pump type should be matched to the existing specification and the operating context. Stainless steel 304 and cast iron are not interchangeable details to overlook; they affect how the pump is specified alongside the rest of the water supply system and pump installation components.
Self-priming and pressure controller options
Some DAB EuroInox multistage water pumps are self-priming. One example, the DAB Multi-stage centrifugal pump, EUROINOX, with pressure controller, combines stainless steel 304 construction with a 1 inch female thread x male thread connection and 230VAC supply.
Connection formats, pressure ratings and voltage
Connections include female thread, female thread x male thread and DIN flange. Threaded options include 1 inch female thread and 1 1/4 x 1 female thread arrangements. A flanged option is represented by the Rovatti Multi-stage centrifugal pump, horizontal, ME, with DN65 x DN50 DIN flange connections.
Pressure ratings include 7 bar, 11 bar and 27 bar. Electrical details include 230VAC, 230/400VAC and 400VAC, depending on the model. These details are important when comparing high pressure horizontal pumps or commercial pump units, because the pump must correspond with the intended pressure requirement and available power supply.
Threaded pump connections
Threaded horizontal pressure pumps can suit installations where existing pipework or fittings use matching thread connections. Foras and DAB models include female thread arrangements, while selected DAB EuroInox models combine female thread and male thread connection details. Before ordering, check the exact connection size and format against the surrounding pipework.
Flanged pump connections
DIN flange models are relevant where flanged pipework is specified. The Rovatti ME example uses cast iron construction and DN65 x DN50 DIN flange connections, with a stated pressure rating of 27 bar and 400VAC supply. Flange dimensions, pressure requirement and voltage should be confirmed together to avoid a mismatch at installation.
Practical selection considerations
Select horizontal centrifugal pumps by working from the installation requirement rather than only from the pump type. Start with the pressure rating, then confirm the connection arrangement, construction material and voltage. If a pressure controller is required, choose a model where that feature is included in the product title, such as the DAB EuroInox version with press control.
For compact multi-stage pumping equipment in water supply systems, compatibility with adjacent pump installation components is essential. The pump connection must match the pipework, and the voltage must suit the electrical supply. The pressure rating should be checked against the required system pressure before comparing price or variant count.
Related pump choices
For stainless steel 304 threaded pump construction, the Foras Multi-stage centrifugal pump, horizontal, Plus 3S is one relevant horizontal model with a 1 inch female thread connection and a 7 bar rating. For cast iron threaded construction, Foras KB and MON120 models provide centrifugal and multi-stage centrifugal alternatives. For flanged high pressure horizontal pumps, Rovatti ME models support DIN flange connection requirements.
