DEEP SUCTION ELECTRIC PUMPSThe self-priming centrifugal deep suction electric pumps series JAP are designed to pump clean water from wells with a minimum diameter of 4" when the water level is deeper than 8 m.
MAIN PERFORMANCE- Liquid temperature: up to 35 °C for domestic use (CEI EN 60335-2-41) or up to 60 °C for other uses. Ambient temperature up to 40 °C.
- Flow rate: up to ~3.6 m3/h.
- Maximum head: up to ~50 m.
TECHNICAL FEATURES- Pump body: cast iron G20 with anti-corrosive coating.
- Motor bracket: die-cast aluminium UNI 5076 (cast iron for JAP 150-200).
- Ejector: cast iron G20 with anti-corrosive coating.
- Diffusers, nozzle and Venturi tube: techno-polymer.
- Impellers: polymer (stamped brass UNI-EN 12165 available on demand).
- Pump shaft: stainless steel AISI 304 (AISI 420 F for JAP 80-100).
- Mechanical seal: carbon-ceramic.
MOTORControl motors are asynchronous, squirrel-cage type, closed with external ventilation.
- Single-phase models include built-in motor protection and permanently connected capacitor.
- Three-phase models require motor protection installed by the customer; use equipment compliant with current standards.
- Insulation class: F — Duty: S1 — Degree of protection: IP44.
- Terminal board protection: IP54.
TYPICAL APPLICATIONS- Pumping clean water from deep wells.
- Domestic and civil water supply, tank filling and storage, well installations.
