I. purpose

Suitable for conveying fuel oil, lubricating oil, hydraulic oil or other lubricating liquid, the medium shall not contain any abrasive particles and substances corrosive to pump materials.


II. Main areas of application

SPF series pumps are used as fuel pumps for conveying, pressurizing and fuel fired furnaces in fuel systems.

Used as a transport and oil feeding pump in an oil delivery system;

In all industrial fields can be used as lubricating oil pump;

Used for hydraulic pumps in various hydraulic transmission devices;


structure

SPF pump is self-priming self-sucking three-screw pump, hardened screw, installed in a replaceable bushing operation. 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 with the help of the clearance between the balance piston and the shaft sleeve, the high-pressure cavity and the seal cavity are separated. There is a mechanical seal in the sealing cavity, and the oil return hole in the cavity is connected with the suction cavity of the pump. Therefore, it is not affected by discharge pressure.

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

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

Allowable temperature 150 ℃ (supply only one specification of type 20)

Allowable working pressure 1.0 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

Motor

The frequency of the motor is 50HZ. if there is no other change, it can work under the 60HZ power supply.
