CALPEDA MXS Stainless Steel Multistage Pumps.

Applications

• For water supply from wells, tanks or reservoirs.
• For domestic use, for civil and industrial applications, for garden use and irrigation. Utilization of rain water.

Construction

• Close coupled multi-stage submersible pumps in chrome-nickel stainless steel, with motor shields in brass.
• Hydraulic part under the motor and motor cooled by the pumped water for safe operation also with the pump only partially immersed.
• Double shaft seal with interposed oil chamber.
• The suction strainer prevents solids bigger than 2.5mm grain size from entering the pump.

Operating Conditions

• Water temperature up to 35°C
• Minimum internal diameter of well: 132mm.
• Minimum immersion depth: 100mm.
• Maximum immersion depth: 20m.
