Well pump dab PULSAR DRY
Well pump dab PULSAR DRYPULSAR DRY pumps are designed for domestic water supply systems from wells, storage tanks and pressure boosting systems. The low noise level allows these pumps to be used in pressure boosting systems in unventilated rooms or areas prone to flooding.
TECHNICAL CHARACTERISTICS
- Operating range: flow from 0.9 to 7.2 m3/h, pressure up to 86 m.
- Max. permissible sand content: 50 g/m3.
- Degree of protection: IP 68.
- Insulation class: F.
- Liquid temperature range: from 0 °C to +40 °C.
- Maximum immersion depth: 20 m.
- Power cable: detachable cable H07RN-F 15 m long with plug SCHUKO EEC 7-VII-UNEL 47166-68 for single-phase version. Single-phase models can be equipped with a built-in float switch for automatic operation.
DESIGN FEATURES
The multi-stage hydraulic part is located on the electric motor shaft, cooled by the pumped liquid. Impellers, diffusers, filter and oil chamber housing – wear-resistant thermoplastic. The pump housing, suction and connecting pipes, and the motor shaft are made of AISI 304 stainless steel. The motor support is made of brass, protected from corrosion by a zinc coating. Seals-NBR. Screws – stainless steel. Double mechanical seal in the oil chamber: ceramic/graphite on the motor side and silicon carbide/silicon carbide on the hydraulic side. The pumps are equipped with a water-cooled asynchronous electric motor with continuous operation (S1). To ensure low noise levels and long service life, the rotor rotates on oversized bearings filled with grease for life. The version with a single-phase electric motor has built-in overload protection. To protect the three-phase motor, overload protection must be provided in accordance with current regulations. Manufactured in accordance with IEC 2-3 and IEC 61-69 (EN 60335-2-41) standards.
