Lowara pumps and system solutions
Lowara product families for borehole pumping, submersible drives, pressure boosting, circulation and drainage. Match your operating conditions to technical data, with model information and PDF documents on the same product page.
From application to product family
CEA, CA, CO, e-NSC and other end-suction families have different impeller, material and connection options. Multistage families such as e-SV or e-HM can be assessed for higher-head duties. Suction geometry and stage count are different classifications: CA is also characterised by its two impellers. First establish minimum, normal and maximum flow and the corresponding system head. Then verify the candidate family on the exact model curve. Catalogue maximum flow and maximum head are not one duty point.
Circulation, boosting and drainage are different duties
For e-LNE, e-LNT and ecocirc families, assess closed-circuit pipe and equipment losses; building height is not simply added to pump head. Boosters instead require simultaneous demand, the highest outlet and minimum inlet pressure. For submersible families such as DOC, DIWA and DOMO, check the fluid, solids, fibres and minimum liquid level separately. Matching motor power does not establish equivalence. Temperature and liquid chemistry also influence seal and elastomer selection; stainless construction does not suit every fluid.
Prepare for a quotation and technical assessment
Match documents to the full model code, frequency, language and revision. Data sheets define operating ranges; manuals describe installation, cooling, protection and commissioning conditions. For replacement equipment, share the nameplate, measured flow and pressure, connection dimensions and installation details. For new projects include operating hours, control requirements, standby strategy and available space. These details help prepare comparable quotations at the same duty point and equipment scope.

Stage count alone does not determine selection. Verify duty point, minimum flow, inlet pressure and seal choice against manufacturer curves.
In-line & circulation pumps
Circuit pressure loss, fluid temperature and glycol concentration influence selection. Check compatibility with connection dimensions and control strategy.

Borehole pumps
Z10 / Z12 / ZR10 / ZR12
High-flow multistage borehole pumps in the 10- and 12-inch classesSplit-case pumps
Double-suction construction still requires a properly designed suction line. Assess NPSH, pipe loads, baseplate and coupling alignment during design.
Pressure boosting systems
Assess simultaneous demand, minimum inlet pressure, redundancy and available space together. Vessel capacity and controls are application-specific.
Fire-fighting pumps
Confirm the applicable standard, approval requirements and hydraulic calculation with the project designer. A product family name is not a substitute for whole-system compliance.
Selection and operating guides
Lowara e-SV selection: data and example for a vertical multistage pump
Do not select from the e-SV family using a single range maximum. Bring flow, system head, NPSH, materials and controls together in a worked example.
Pump suction piping: air pockets, loss and tightness
Assess suction-pipe rise, connections and total loss at the lowest tank level, then correct an illustrative installation fault.
Closed-loop circulator selection: how to determine flow and loss
Building height is not pump head in a filled closed loop. Calculate flow from thermal load and head from the critical circuit in a worked example.
Lowara frequently asked questions
Are e-SV and e-LNE interchangeable?+
e-SV is vertical multistage and e-LNE is single-stage in-line. Suitability requires verification of duty, fluid, installation and controls. Motor power alone does not establish equivalence.
Where can I download Lowara PDFs?+
Open the relevant product below. PDFs in its Technical Documents section are served through the Parla site. Check model and document revision.
Is flow alone sufficient for selection?+
No. Total head, suction conditions, fluid properties, temperature, power supply and operating profile are also required. Provide both low- and high-demand duties.
