Close-coupled submersible pumps Applications • Water supply from rain water tanks or reservoirs, 6” wells, basins and watercourses. • Sprinkler systems. • Pressure boosting with pump inserted directly in tank or well, to avoid suction problems and noise. Specifications • Delivery: up to 7,5 m3/h. • Head: up to 80 m. • Maximum pump overall diameter: 128 mm. • Maximum immersion depth: 20 m. • Maximum permissible quantity of suspended sand: 25 g/m3. • Passage of solids up to 2.5 mm. • Delivery port: Rp 1”1/4. • Rated motor power: 0.55 to 1.1 kW.

• Single-phase motor: 220-240 V, 50 Hz, built-in automatic reset overload protection, built-in capacitor.
• Three-phase motor: 380-415 V, 50 Hz; overload protection to be provided by user and installed in the control box (see control box section).
• Maximum supply voltage variations: ±5%
• Class F insulation.
• Can also operate in horizontal position.
• Maximum number of starts per hour, at regular intervals:
25 for motors up to 0.9 kW.
20 for 1.1 kW motors.
• Maximum temperature of water in contact with the motor: 40°C (continuous use).

Construction features
• Close-coupled, multiple-impeller submersible electric pump. The liquid end is located under the motor, which is cooled by the pumped liquid.
• Dry motor The electric motor is protected by a double seal with an oil chamber.

Sealing system
The silicon carbide mechanical seal, highly resistant to abrasion and wear, together with the second mechanical seal, lubricated thanks
to the special configuration of the oil chambers, guarantee long-lasting reliability. The oil used complies with FDA (FOOD AND DRUG ADMINISTRATION) standards.
• Single-phase models with float (SCUBA G series) are also available.
• Kit including pump+Hydrovar Watercooled inverter available for the following models: HVW/SC207T - HVWSC407T.
