Industrial Pump
Description
SRS series oil cooling submersible screw centrifugal pumps can go beyond the limits of classical centrifugal pumps, and even into the application area of positive displacement pumps. the construction is suitable for the handling of solids in suspension and viscous liquids, as well as for applications with larger negative suction heads.
the shape of the inlet edge creates an "inducer effect", which makes a large negative suction head possible (or a higher transportation media temperature). a pronounced screw shape creates a displacement effect with high viscosities, which makes possible the handling of viscous liquids well into the displacement pump application range.
Operating Data(50Hz)
.Fluid: raw sewage and industrial wastewater with grid filtration, long fiber, transporting activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.
.Working temperature range: -10℃ ~ 80℃.
When working temperature exceeds 80℃，shall clarify clearly and in advance.
.Operating pressure:
PN1.0 MPa - Hydrostatic test pressure = PN1.6MPa
Application
.Sewage field:
Raw sewage and industrial wastewater without grid filtration, long fibers.
Transporting activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.
.Chemical industry:
Conveying chemical pulp containing particles.
Transporting oil water mixtures to transport chemicals with a viscosity of up to 4000 cSt has a much lower correction factor than other centrifugal pumps.
.Pulp and Paper Industry:
Flexible conveying of pulp containing fibers.
Conveying long paper fibers
Features and Benefits
| Design Features | .Volute casing The volute casing is designed based on non-blocking in large flow channels, flange standards comply with ISO7005.1 PN10 RF. .Suction casing The high-precision combination design of the suction chamber and screw centrifugal impeller ensures higher pump efficiency. The specially designed suction wear-resistant lining structure ensures longer pump service life and lower operating costs. .Oil Cooling Jackets The circulation pump in the oil cooling reservoir, which runs synchronously with the motor, guarantees absolute operational reliability. The process heat is transferred to the transported medium via cooling ribs on the rear of the hydraulic system. Therefore no special cooling channels are necessary for this in the oil chamber. The channels that are common used often become coated with sludge, thereby hindering an efficient heat transfer and leading to undesirable overheating. .Operational Safety Components (Monitoring) Built-in temperature sensor, moisture detector and other neccessary components to effectively monitor the abnormal status of pump and motor thus providing more safety and reliablity to the whole unit. |
