Whether it’s an indoor swimming pool, an outdoor swimming pool or a hotel pool: reliable pool water circulation is the foundation of effective water treatment. The pumps circulate the water through the treatment circuit and back into the pool. The flow rate, energy consumption and operational reliability must be tailored to the requirements of the system.
SPECK offers suitable pump solutions for different pool sizes, water qualities and installation scenarios. A range of designs, carefully selected materials and appropriate drive and control concepts enable customised configurations. Service-friendly designs simplify maintenance whilst the system is in operation. In this way, our pumps support reliable and cost-effective swimming pool operations – from new builds to the modernisation of existing facilities.

Technical Specifications
The flow rate, design and materials are tailored to the treatment cycle and the water quality of your plant.
Designs and series
The following pump series, amongst others, are available for pool water circulation:
- BADU Resort: Block pumps with an integrated fibre trap and plastic casing, suitable for use in hotels, spa facilities and larger swimming pool complexes, for example.
- BADU Block: Normal-suction, single-stage volute casing pumps in a vertical monobloc design with a pre-filter. Depending on the version, various combinations of metallic materials are available.
- BADU Block Multi: Normal-suction, single-stage volute casing pumps in a vertical monobloc design with pump and filter casings made from engineering plastics.
The selection depends on the required operating point, the water quality and the spatial conditions.
Hydraulic design and speed control
The pump design takes into account the required flow rate and the pressure losses in the treatment circuit. With the BADU Block and BADU Block Multi, the impeller can be adapted to the respective operating point. Performance curves, dimensional drawings and material combinations are available in the SPECK SELECT design programme.
Suitable frequency converters enable different speeds for the intended operating conditions, such as circulation, filter backwashing and rinse cycles. The flow rates required for water treatment form the basis for the control system.
- BADU Eco Drive II: For compatible pumps and motor power ratings, including those within the BADU Resort series.
- Control: Depending on the system, via digital inputs, 0–10 V or 4–20 mA.
- BADU Resort-PM: Models with synchronous drive for operation via a suitable external control system.
Materials, waterproofing and specific water qualities
The choice of materials takes into account the composition of the water, the temperature and the operating conditions. In this context, the casing, impeller, seals and other components in contact with the fluid are considered as a whole.
- Plastic versions: BADU Resort and BADU Block Multi use different technical or reinforced plastics, depending on the component.
- Metal versions: In the case of BADU Block, grey cast iron and copper-tin alloys, amongst others, are used depending on the version.
- BADU Resort-AK: An intermediate housing and a labyrinth disc structurally separate the seal chamber from the motor. This protects the motor and bearings from any escaping fluid, as well as from crystallising salts and minerals.
- Special requirements: Special sealing materials are available on request for BADU Resort-AK. Suitability for water containing salt, brine or minerals is determined on the basis of the specific operating conditions.
Pre-filters and maintenance
Integrated fibre traps or pre-filters prevent coarse contaminants from entering the pump’s hydraulic system. The size depends on the respective series and model.
- BADU Resort: Fibre trap capacity approx. 10 litres; suction strainer mesh size approx. 3.4 × 3.2 mm.
- BADU Block Multi: Filter housing with a capacity of approx. 9 or 19 litres, depending on the size; mesh hole diameter approx. 3 mm.
- BADU Block: Filter housing with a capacity of approx. 13, 29 or 71 litres, depending on the size; screen hole diameter approx. 3 mm.
With the BADU Block and BADU Block Multi, the modular design facilitates work on the drive unit whilst the pipework connections remain in place. Sufficient access must be provided during plant design to allow for cleaning and maintenance.
