Detail view of dual line dose feeder
Description
Dual line grease feeder is made of steel having two input ports connected with two outlet lines of pumping station. Outlet ports of dose feeder are connected to lubrication points by means of tubing (pipelines). The connection of dose feeders have been shown in the flow diagram. At the another side of dose feeder an adjusting screw has been provided for adjusting the quantity of grease as per requirement. Functioning of each dose feeder can be noticed by the movement of indicating pin. Dose feeder is available in discharge range of 0.5 to 5 gm/cycle (adjustable). It comes with different number of outlets i.e. 1/ 2 / 3 and 4.
What Is a Dual Line Dose Feeder?
A dual line dose feeder is a metering device used in dual-line centralized grease lubrication systems. It receives pressurized grease alternately from two main supply lines (Line A and Line B) and dispenses a precise, adjustable volume of grease to a single lubrication point on each cycle. The two-line design allows the system to operate continuously — while one line pressurizes and delivers grease, the other line vents, resetting the feeders for the next cycle.
SP Engineers supplies dual line dose feeders from Faridabad, India — suitable for steel plants, cement plants, rolling mills, and other heavy-duty applications where large numbers of lubrication points must be served reliably from a central pump station.
Key Advantages of Dual Line Systems
- Each feeder delivers a metered dose independently — one blocked point does not affect others
- Adjustable output from 0.5 to 5 g/cycle using the adjustment screw on each feeder
- Visual indication pin confirms that the feeder has cycled — easy maintenance check
- Available with 1, 2, 3, or 4 outlets per feeder body
- Suitable for long distribution lines — dual line systems work over distances up to 100 m from the pump
- Compatible with NLGI 0, 1, and 2 greases
Dual Line Dose Feeder vs Progressive Distributor Block
| Feature | Dual Line Dose Feeder | Progressive Distributor Block |
|---|---|---|
| Operating principle | Two alternating pressure lines | Single pressure line, sequential discharge |
| Fault isolation | One blocked point does not stop others | One blocked point stops the entire block |
| Distance from pump | Up to 100 m | Up to 30–40 m typically |
| Best for | Large machines, heavy industry | Smaller machines, CNC, presses |
