Applicable scope

For enterprises and institutions such as: bath center, district heating, enterprises that make use of geothermal energy or for groundwater extraction High temperature hot water, according to the different diameter of well we have different specifications for the user to choose. The device has low noise。 High efficiency, energy saving. Technical parameters] 1: the working temperature range: +5 to +105 ℃ 2: solid impurity content (mass ratio) is less than 0.01% 3: pH value (PH) 6.5-8.5 4: hydrogen sulfide content is not more than 1.5mg/L 5: the chloride ion content is not more than 400mg/L 6: Pump must be used completely in water. Motor parameters Submersible motor cable length: 3m. If users need cable to be extended, they can call us in advance. The submersible motor is lubricated by clean water, so the motor chamber must be filled with clean water before use, (Note: otherwise service life of the motor will be reduced) if you forget to fill water to the motor it will quickly burn out. Motor protection grade: IPX8 Eectromagnetic wire adopts high temperature resistance and water proof cable. Power supply 380V, error is less than ± 5%, frequency 50HZ, error is less than ± 1%, if a customer need special voltage or frequency, he needs to inform us in advance. Material Impeller: cast iron HT200, or tin bronze (various grades) such as: ZCuSn3Zn8Pb6Ni1 The pump casing: cast iron or stainless steel, such as: HT200, 2Gr13.304 Pump shaft: cold drawn steel chrome plated or stainless steel, 2Gr13 (1050 ℃ tempering, strengthen torque) The motor seal: rubber O ring; machine sealing Motor expansion adjustment: rubber material Advantages Carefully assembly in the factory ensures quick and reliable installation Multiple impeller, low noise Built-in check valve avoids the impact from water hammer. Single-stage pump with high lift can reduce the height of the whole unit and increase operation stability. The pump shaft’s diameter is 28mm increasing the anti torque properties. The pump shaft is made from more durable natural rubber material, and with a hard shell made of imported materials
