Application of SPF three screw pump

Suitable for thermal power plant, glass cement, asphalt mixing station, building materials factory, shipbuilding, chemical, pharmaceutical, asphalt mixing plant, steel plant, blast furnace, high pressure steam boiler, oil boiler, boiler, shipbuilding industry, diesel engine, turbine boiler fuel delivery system or burner fuel delivery main fuel jet fuel application; oil, diesel oil, heavy oil, lubricating oil, hydraulic oil, diesel, gasoline (MDO, MGO) HFO, heavy fuel, vehicle fuel, bio oil or other liquid lubricating, the transmission medium not containing any abrasive particles and the corrosion of pump material.

SPF series three-screw pumps are widely used in oil transportation and injection, as well as in industrial pipeline transportation as fuel oil transport and regulation pumps.And more for all kinds of asphalt mixing plant and asphalt mixing plant burner and medium and small gear box gear reducer hydraulic lubrication equipment.

Can provide complete supply of motor screw pump assembly, with oil absorption pipes and support, as well as complete test reports;

Can provide pressure relief valve sets and other supporting accessories;


II. Main areas of application
SPF series three-screw pump is used as fuel pump in burner fuel system for conveying, injection, supercharging and fuel oil furnace.
It is used in the oil transportation system as the booster pump, the fuel injection pump and the diesel ignition pump.
In all industrial fields can be used as lubricating oil pump;
Used for hydraulic pumps in various hydraulic transmission devices;


Ⅲ, structure
The SPF pump is a self-priming three-screw pump with built-in bearing. The screw is treated by nitridation and hardened on the surface. The surface of the screw pump is specially treated and the hardness is 63HRC. The pump is operated in a replaceable bushing. The main rod adopts hydraulic balance, the axial force of the rod is supported on the back cover and rotates by hydraulic force, so the screw face only transmits hydraulic torque, does not bear force, and has no wear. For all transmission parts, it is lubricated by the conveying medium.The radial direction of the main rod is located by the balance piston, and the high pressure cavity and the seal cavity are separated by the clearance between the balance piston and the shaft sleeve. There is a mechanical seal in the seal cavity, the oil return hole in the cavity and the pump The suction cavity is connected and is therefore not affected by the discharge pressure. All sliding parts are lubricated by medium. Shaft seal is mechanical seal, no leakage and no maintenance. The sealing chamber and the suction chamber are connected by an internal loop. The output pressure on the shaft seal is independent and only produces absorption pressure. Pump and motor are connected by bracket. When the spiral rotates, the three spirals of the seal chamber perform a complete continuous axial motion. The rotation of the spiral does not cause vibration. Outside the extrusion, the capacity of the seal chamber remains unchanged. The stability of structure design and operation ensures low noise and no pulsation of screw pump operation.
The pump is coupled and driven by the bracket, the coupling and the motor, ( e.g., size 20 ), or wall mounted ( e.g. size 40 ).


IV. Characteristics
a radial or axial oil suction port , an SAE flange BSPP or a screw connection can be selected ;
Screw pump external sheath (optional) material for AMSE standard, can be made according to API standard;
Screw hardness is 63HRC, ultra-precision machining;
The lowest allowable viscosity of the medium is 2 cst, the maximum is 1000 cstand the maximum allowable particulate matter is 30 um.
The maximum pressure of screw pump is 4 MPA;
Flow range: 0-120L / min

1. Operation
When the active screw of the helical surface of the special profile is rotated, the dynamic seal chamber will draw the liquid from the suction port and continue along the axial direction, conveying it to the outlet without pulsation.

2. Noise, pulsation
The structure and operation stability of the screw pump ensures the low noise and no pulsation of the pump.

Shaft seal
The pump is mechanically sealed, and the mechanical seal does not need maintenance.

3. construction(al) material(s)

Dynamic ring impregnated resin graphite

Static ring high carbon chromium steel

"O" ring fluorine rubber

Spring stainless steel

Metal element stainless steel

4. temperature and pressure range

Allow working pressure 4 MPa
Please consult with the factory for higher use temperature
Working pressure under different viscosity and rotational speed, according to performance parameter table.

5. Safety valve
Each pump is equipped with a safety valve as an overload protection device.

6. import and export flanges
Imported flange: PN16DIN2533 GB2555-81)
Outlet flange: PN40DIN2535 / GB2555-81)

7. Installation
SPF pumps can be installed anywhere, for safety reasons, the motor is not allowed under the pump.

8. Power matching
Various types of motor or other drives are connected to the pump by coupling.
Three phase AC motor, its protection grade is IP44, insulation grade is B, power and main connection dimensions are according to Y series
