DUAL – LINE SYSTEMS :

The Pump delivery & relief lines are both connected to the change – over valve. This valve system allows the two main lines to pressurize and relieve alternatively. All metering elements are piped into both main lines. The supply of lubricant to the lubrication points is ensured when both main lines have been repressurized and relived in correct sequence. An end pressure relay situated at the end of the main line senses the differential pressure between the two lines and regulates the change over. Dual Line Systems provide reliable lubrication for large and extended installations, on heavy duty plant and equipment working under adverse conditions.

Manual Pumps :

"AFMC' make manually operated pump is a basic lubricant compressor for the manually operated Two-line centralised lubrication system. Our Model Monomatic series is a semi automatic pump having an externally mounted four way self reversing valve Model No. ‘COV-2’ for supplying lubricant alternatively to the two supply lines and our Duomatic series pump has an in-built push-pull type four way flow directing valve for supplying the lubricant alternatively to the two supply lines.The pump is complete with reservoir, tell-tale rod,pressure gauge, line filter, filler connection and mounting bracket. For further details refer to the table below :

Automatic Pumps :

An electrically operated End-Of-line system consists of a central pumping unit with a flow –directing valve, two main Supply Lines and suitably placed “SUR-LUB” Metering Manifolds.
The central unit is high pressure plunger type reciprocating pump driven by an electric motor. The suitably placed metering manifolds has a built in and Worm and Worm-wheel type reduction gear to obtain correct cam shaft speed. The reversing Flow Directing Valve directs the lubricant into one each of the main lines in turn , while the other line is in relief. After the pressurised line injects the lubricant to the bearings through the Metering Manifolds, pressure increases in the line to a preset valve, and operates a Pressure Control Valve located at the end of the longest branch (before the last Metering Manifold) or alternatively at the central pumping station. Operation of the Pressure Control Valve stops the Electrical Motor and activates the reversing Flow Directing Valve, so that the next cycle the lubricant many be delivered through the other main line. In this range our models include Duotrol 60/120/133/150/300/500 C.C. min.
A relay logic Control Panel is supplied together with the Pump to co-ordinate the entire electrical operation and also the resumption of successive cycles at desired intervals. The Control Panel is also designed to give Audio-Visual warning signals, in case, due to any reason, a lubricating cycle is not found to be completed within a preset stipulated period. Restarting successive cycles of lubrication may be done in any of the following ways:-

(i) Automatically at regular intervals by help of an electrical Time Clock.
(ii) Electrically inter-locked with the parent machine to make a cycle of lubrication, whenever a preselected movement of the parent machine takes place.
(iii) Whenever desired, by help of an over-riding Push Button.

Metering Manifolds :

AFMC manufactures a wide range of metering manifolds (Dose feeders) which include product equivalents of various world renowned manufacturers. We manufacture product equivalents of Lincoln , Delimon, Daikin, IHI, Samsung, Farval USA, Farval, UK etc. All the Models we manufacture vary in dimensions, inlet & outlet threads and discharge which make them equivalent to their counterparts and also provides a wide variety of combinations which suit the client’s exact requirements.

Single-Outlet Series:

"AFMC" metering manifolds are used as positive metering devices in Two-Line lubrication systems.The metered injection of lubricant at high pressure is achieved by means of ingenuous valvepiston combination.Discharge from each outlet can be individually adjusted by means of screws located at the top of the indicator housing.Indicator stems attached to pistons give positive visual indication of operation .Special seals prevent leakage past indicator stems.

Max Working Pressure – 400 bar.

Double Outlet Series

'AFMC' Two-line metering manifolds provide an economic means for positive metering of lubrications into bearings.The ingenuous pistonvalve combination in this series is so constructed that each piston is capable of lubricating two bearings in two consecutive lubrication cycles. Discharge from each piston can be adjusted by means of adjusting screws located at the top of each indicator housing. Floating indicator stems attached to each piston gives positive indication of operation. Special seals prevent leakage past indicator stems.

Max Working Pressure – 400 bar.
