Product catalog summary

Specifications:
The document describes multi-stage centrifugal submersible pumps with a chrome-nickel stainless steel pump jacket and a vertical delivery port. The motor is cooled by water passing between the motor jacket and the external jacket, and features a double shaft seal with an oil chamber.

Applications:
These pumps are suitable for clean water containing solids up to 2 mm in grain size. They can be used for draining rooms, emptying tanks, extracting water from ponds, streams, or pits, and for irrigation purposes. For outdoor use, a power supply cable of at least 10 m is recommended, following EN 60 335-2-41 standards.

Operating Conditions:
The pumps can handle liquid temperatures up to 35°C, with a maximum immersion depth of 5 m and a minimum water level of 100 mm with a float. They are designed for continuous duty.

Motor Specifications:
The pumps are equipped with a 2-pole induction motor operating at 50 Hz (n ≈ 2900 rpm). They are available in three-phase (230 V ± 10% and 400 V ± 10%) and single-phase (230 V) versions, with features like a float switch, thermal protector, and incorporated capacitor. The motor has an insulation class F and protection IP X8 for continuous immersion.

Materials:
Key components include a pump casing and impeller made of PPO-GF20 (Noryl), a motor jacket of chrome-nickel steel (AISI 304), and a shaft of chrome-nickel steel (AISI 303). The mechanical seal is made of ceramic alumina/carbon/NBR, and the seal lubrication oil is suitable for food/pharmaceutical machinery.

Performance and Dimensions:
The document provides detailed performance charts and dimensions for various pump models (MP 201, MP 202, MP 203, MP 401, MP 402, MPM 201, MPM 202, MPM 203, MPM 401, MPM 402). It includes information on power input/output, cable specifications, and installation examples.

Additional Features:
The pumps feature a suction strainer allowing solids up to 2 mm, a double shaft seal with an oil chamber, and a vertical delivery port for easy installation. The float switch can be adjusted for start/stop levels, and the handle is made of polypropylene. The motor is cooled by water passing between the motor jacket and the external jacket, and the shaft sleeve is made of ceramic stainless steel.
