Submersible Engineering Drainage Sewage Sludge Pump

Hydroman^® Submersible Engineering Drainage Sewage Sludge Pump is engineered for demanding dewatering and sludge-handling operations in civil engineering, infrastructure, mining, and tunneling environments. Designed for submersion in high-solid-content and abrasive fluids, hydroman^® submersible wastewater pump offers robust performance, non-clogging operation, and long-lasting durability in harsh site conditions.

Hydroman^® Submersible Engineering Drainage Sewage Sludge Pump Technical Specifications

Hydroman^® Submersible Engineering Drainage Sewage Sludge Pump Conditions of Use

• The medium temperature should not be over 60℃, the density 1200Kg/m3, and the PH value within 5-9.

• During running, the pump must not be lower than the lowest liquid level, see"lowest liquid level" in the drawing of installation dimensions (covering the automatic cooling system),means lowest liquid level without no automatic cooling system.
• Rated voltage 380V, rated frequency 50Hz. The motor can run successfully only under the condition the deviations of both rated voltage and frequency are not over ±5%.

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

Hydroman^® Submersible Engineering Drainage Sewage Sludge Pump Check of Use

• Carefully check if thee is any deformation or damage with the pump and any looseness or fall-off with the fasteners during transport, storage and installation.
• Check if any damage or fracture with the cable,if the seal on its inlet intact and make a proper treatment in time if any possible leakage or bad seal is found.
• Measure the dielectricresistance between the phases and between the phase and ground with a 500V megohm 2 meter, the value of which has not to be lower than megohm,otherwise a drying treatment must be taken for the statorwinding of the motor with a temperature not over 120℃ or notify the manufacturer for help.
• Check if there is oil in the oil chamber and do not stop filling it until it overflows on the filler.
• Check if the serew cork and sealing pad on the oil chamber are full and if the serew cork presses the sealing pad tightly.

• Check if the impeller rotates flexibly.

• Check if the power device safe, reliable or normal and if the grounding wire inside of the cable reliably grounded.

• Before placing the pump in the pool, check if it is in a correct. Direction of rotation by way of dot moving and cut off the power andchange the U,V, W three wires with any two of which in the electric control cabinet if not correct.

Hydroman^® Submersible Engineering Drainage Sewage Sludge Pump Regular Checking

• Periodically check the dielectric resistance between phases and between phase and ground, the value of which should not be lower than 2 megohm, otherwise it has to be removed to overhaul, and, at the same time, check if the grounding is secured and reliable.
• Replace the seal ring with a new one when the max.interval of it, mounted on the impeller neck and pump casing,is over 2mm.
• After half a year running ofthe pump under the provided working medium condition,check the state of the oil chamber and replace it with Nl0 mechanical oil if it shows emulsifed state. It is possible that the mechanical seal on the pump. Side is made damaged when the leakage probe gives a warning with the pump running for a short time after the oil replacement and replace it at once. More often check the pump when it is used under a very adverse working condition.
• After one year work of the pump under the normal working condi tion, a big overhaul must be taken for replacing the wornout parts, checking the fasteners and supplementing or replacing the grease on the bearing so as to ensure a good lubrication of the pump during its running.
• To disassemble, do not knock at it at will in order to avoid damaging the seal and do not allow non-skilled persons to do that in order not cause it leaking or the motor damaged.
