Specifications:
The document describes multi-stage centrifugal submersible pumps with an external jacket made of chrome-nickel stainless steel. These pumps feature a vertical delivery port and are cooled by the pumped water. They include a double shaft seal with an oil chamber for enhanced protection.

Applications:
These pumps are suitable for clean water containing solids up to 2 mm in 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 meters is recommended.

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

Motor Specifications:
The pumps are equipped with a 2-pole induction motor operating at 60 Hz with speeds around 3450 rpm. They are available in three-phase (220V, 380V, 440V) and single-phase (110V, 127V, 220V) configurations. The motors include features like a thermal protector, incorporated capacitor, and are constructed according to EN standards.

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

Additional Features:
Optional features include different voltages, mechanical seals, cable lengths, and a vertical magnetic float switch. The motor can also be adapted for operation with a frequency converter.

Performance and Dimensions:
The document provides detailed performance charts and dimensions for various pump models, indicating their flow rates, head, and power consumption.

Installation:
The pumps feature a vertical, upward delivery port for easy installation in small pits. They include a suction strainer that allows the passage of solids up to 2 mm and an easy-to-adjust float switch for controlling pump levels.
