Submersible borehole pumps for wells with a diameter of 4 inches and more with a wide range of flow and pressure characteristics. Designed for domestic and industrial water supply systems, for supplying water to autoclaves and tanks, for installation in fire-fighting systems and high-pressure flushing systems, for agricultural irrigation systems.
TECHNICAL CHARACTERISTICS
- Pumped liquid: clean, without solid inclusions or abrasive particles, chemically neutral, similar in characteristics to water.
- Fluid temperature range: 0 ˚C to +40 ˚C.
- Motor protection degree: IP 68 .
- Insulation class: F.
- Special versions on request: electric motors for other voltages and/or frequencies
- Maximum permissible sand content in the pumped liquid: 120 g/m3 (S4A, S4B, S4C, S4D)
300 g/m3 (S4E, S4F) - On request for single-phase model: control unit with additional starting capacitor available (BOOSTER) to increase the starting torque.
DESIGN FEATURES
Caliper (with built-in filter), pressure pipe (with built-in check valve ) and the cable protection strip are made of stainless steel. The TESLA two-pole oil-filled submersible asynchronous electric motor is made entirely of AISI 304 stainless steel. The starter is rewindable. The starting capacitor unit for single-phase models has built-in overload protection with the possibility of manual restart. To protect the three-phase electric motor, overload protection must be provided in accordance with current regulations.
