Pulsar 30/40/50/65/80

Summary

Product Identification

The PULSAR series consists of 5” multi-stage submersible pumps, designed for quiet operation in wells or reservoirs. The hydraulic section is located below the motor, which is cooled by the pumped liquid. These pumps are suitable for pressurized water distribution in domestic systems, small-scale agriculture, and garden irrigation.

Key Features:

• Impellers, diffusers, filter, and oil sump: Scratch-resistant thermoplastic material.
• Outer casing, stator casing, headpiece with socket and washer: AISI 304 steel.
• Rotor shaft extension / Motor shaft: AISI 304 stainless steel.
• Seals: NBR.
• Screws: Stainless steel.
• Double mechanical seal: Ceramic/graphite on the motor side and silicon carbide/silicon carbide on the pump side, with an intermediate oil chamber. (French text also mentions ceramic/carbon on pump side and a sealing ring on motor side, with lubrication by motor cooling liquid).
• Upper support with discharge port and suction strainer in technopolymer.

Available Models (Examples):

• PULSAR 30/50 M-A
• PULSAR 30/50 M-NA
• PULSAR 30/50 T-NA
• PULSAR 40/50 M-A
• PULSAR 40/50 M-NA
