Submersile Dewatering Pump With Float Switch Manufacturers and Suppliers China - Wholesale Price - MILESTONE

pump overview

dewatering pumps are designed to remove not just water but also waste and other small materials from a building to the septic tank or the sewage system.

A float switch is a type of contact liquid level sensor that uses a float to operate a switch. Float switches are commonly used to control other devices such as alarms and pumps when a liquid level rises or falls to a specific point.

Pump feature

1. The medium temperature should not be over 40"C, the density 1200Kg/m, and PH value 5-9 2. During running, the pump must not be lower than the lowest liquid level, V means lowest liquid level without no automatic coo-ling system.

3. Rated voltage 230380V-480V, rated frequency 50Hz/60Hz.

The motor can run successfully only under the condition the deviations of both rated voltage and frequency when they are not over 5%.

4. The maximum diameter of the solid grain going through the pump has not to be larger than 50% of that of the pump outlet.

5.Cooling system

The built-in cooling system can have the pump normally work whether the motor is on or under the liquid surface.

A part of the liquid is extracted to bring out the beat produced by the motor from the pump circulation to the cooling barrel and to the pump casing and, when external cooling is required. The cooling sleeve may be separated from the pump casing. individually connected to the cools system

6. Motor

F class insulation, max working temperatures 155C.and of a protective grade IPX8 with the effective seal.

7. Mechanical seal

Use Bogman mechanical seal of Germany, two ways of the seal are in series with each other and individually work to separate the motor from the pump seal to provide the motor with a dual protection
