Product Overview
Operating data for this 0.25 kW motor includes a maximum flow rate of up to 170 L/Min and a total head reaching up to 8.3 m. Drawing a rated current of 2.3 Amps on a single-phase 240v supply, the unit is equipped with a 5 m submersible power cable. The air-filled 2-pole induction motor is designed for stable service and includes built-in overload protection for winding safety.
Clean water transfer and the emptying of tanks, drums, and small reservoirs are the primary applications for this automated unit. It is IP68 rated for submerged operation up to 5 meters and handles liquid temperatures reaching 50°C in vertical installations. This version utilizes an integrated magnetic switch, allowing for automated start and stop control in narrow pits with limited 200 x 230 mm dimensions.
The hydraulic design features a semi-open centrifugal impeller that facilitates the passage of suspended solids up to 10 mm. This system provides an open flow path to move liquid efficiently through a 32 mm discharge port, maintaining operational stability in domestic dewatering systems. It is engineered for reliability in applications where suspended particles are limited to small particulates found in clean water sources.
Materials include a 304 stainless steel pump casing, motor frame, and impeller paired with an AISI 303 stainless steel shaft. Protection is managed by a mechanical seal in an oil-lubricated chamber featuring Ceramic/Carbon/NBR faces and an upper NBR lip seal. The rotating assembly utilizes sealed ball bearings, and all internal gaskets and O-rings are manufactured from NBR rubber to ensure structural integrity and long-term sealing.
FEATURES
- Magnetic switch enables automated operation in compact sumps where float switches lack clearance.
- Ceramic/Carbon/NBR mechanical seal faces provide reliable sealing in clean water service.
- Upper NBR lip seal offers additional protection against moisture at the motor side.
- NBR rubber O-rings and gaskets maintain watertight integrity across all housing joints.
- Ceramic-coated AISI 303 shaft sleeve enhances wear resistance at the seal interface.
- Built-in capacitor eliminates the need for external starting components.
- 5-meter H05RN-F power cable with 3-pin plug supports immediate installation.
- Class F insulation and IP68 rating protect the motor in submerged conditions.

Where can magnetic switching help in confined sumps?
Compact pits benefit from the magnetic switch on BEST_ONE_MS_304, which supports automatic start and stop control where float-switch clearance is limited.
What maximum head can this unit provide?
During sump emptying, BEST ONE MS 304 develops a maximum head of 8.3 m through its 32 mm discharge port.
Which clean-water transfer duties suit this configuration?
Tank drum and small-reservoir emptying suit BEST-ONE-MS-304, which uses an integrated magnetic switch for level-responsive operation during unattended transfer in narrow pits.
How is the motor powered and protected?
Rated at 0.25 kW, the induction motor in BEST/ONE/MS/304 runs from single-phase 240 V and draws 2.3 Amps with overload protection.
What particle size can pass through its hydraulic path?
The semi-open centrifugal impeller in BESTONEMS304 passes particles up to 10 mm through a 32 mm discharge port during clean-water transfer.
