Miniflow S & MB
Applicators
DESCRIPTION
The Miniflow S Applicator is designed for use either with a conventional big round baler (using 2 nozzles) or a trailed
forage harvester (using 1 or 2 nozzles). The Miniflow MB Applicator has a single nozzle and has been developed specially
for use with mini haylage balers where the small bale size (less than 50kg) and slow baling speed mean that much lower
flow rates are required. Both applicators have proved to be thoroughly reliable in use and are usually supplied for use
with a 200 litre drum but are also available for use with 25 litre cans (special order).
SUPPLIED
1. Submersible motor/pump unit – 12v DC supply
2. Fully variable electronic Control Box (3 amp fuse)
3. Miniflow S - 2 nozzle bodies and 6 sizes of nozzles
Miniflow MB - 1 nozzle body and 4 sizes of nozzles
4. 10 metres PVC tubing (int. Ø ⅜inch)
5. 10 metres electric cable - supplied in one length to be cut as required
6. T-piece (Miniflow S only)
FITTING
The applicator operates from the tractor electrical system, which must have a 12v DC supply. It is important to ensure
that maximum output is being produced by the tractor, otherwise pump output will be reduced and damage to the
applicator may result.
1. Fit the pump unit into an upright 200 litre plastic drum placed as required on the harvester or tractor.
2. Fit the nozzles bodies in suitable positions, eg one nozzle in the chute or two across the pickup. Measure the distance
from the pump to the nozzle body and cut the tubing to the required length. If using two nozzle bodies, cut the
tubing and use the T-piece to join them together and to the pump.
3. Fit the control box in an easily accessible place in the tractor cab.
4. Connect the bullet connectors to the pump motor (red to red, black to black).
5. Measure the distance from the applicator to the control box and cut the electric cable to the required length. Attach
the bare ends of the cable to the ‘pump’ end of the control box (red to red +ve, black to black -ve).
6. Connect the remaining length of cable to the ‘battery’ end of the control box (red to red +ve, black to black -ve).
7. Fasten the crocodile clips to the battery (red to positive, black to negative).
WARNING: IT IS ESSENTIAL TO ENSURE THAT THE BATTERY LEADS ARE CONNECTED TO THE END OF THE
CONTROL BOX MARKED 'BATTERY' AS WRONG CONNECTION WILL CAUSE DAMAGE.

-1-

The applicator is controlled from the tractor cab using the control box. Switch the unit ON then turn the variable SPEED-
knob to adjust the flow rate (see Calibration Chart).
The control box is protected from overload by a 3 amp fuse. This fuse must never be replaced by any other size
or type of fuse or serious damage could occur, either to the applicator or to the tractor's electrical circuits.
FLOWMETER (Optional Extra)
This should be mounted in a convenient position outside the tractor cab but easily visible to the operator. It is graduated
from 1 to 10, the setting being indicated by the position of the float against this scale. The flow is from the bottom to the
top so the tubing from the pump is attached to the bottom and the tube to the nozzle to the top.
OPERATION
1. Select the correct nozzle size from the Calibration Chart and fit into the nozzle body - ensure a tight fit. Check the PVC
tubing for damage and kinks and that the connections are secure and the right way round (never run the pump in
reverse).
2. Make sure there is some additive in the barrel (never run the pump dry).
3. Switch the pump to ON at the control box and adjust the variable SPEED knob to give the required flow rate (see
Calibration Chart)
OUTPUT
The Miniflow applicator is capable of up to 3.5 litres/min (open flow) provided the electrical supply is adequate.
Attachment of tubing, flowmeter, nozzle bodies or nozzles will reduce this.
SAFETY
1. Do not change filters or nozzles while the tractor or harvester/baler is running.
2. Switch the pump to OFF before changing barrels.
MAINTENANCE
1. Always flush out the system with clean water after use.
2. Never allow the pump to stand for long storage periods while filled with additive.
3. Store in a clean, dry place.
4. Never use a higher rated fuse.
5. Do not allow the tubing to become kinked.

MiniFlow S Applicator
Calibration
for forage harvesters - using one nozzle
CALCULATING THE FLOW RATE REQUIRED
Measure the time taken to fill a trailer. Only include actual pick-up time, not time taken turning, etc.
Calculate the flow rate required as follows:
1. Harvest rate (tonnes/min) = weight of grass (tonnes)
time to fill trailer (mins)
2. Flow rate (litres/min) = harvest rate (tonnes/min) x required application rate (litres/tonne)
CHOOSING THE CORRECT NOZZLES AND CONTROL BOX SETTING
Choose the flow rate in the table below that is closest to the flow rate determined above. Then read off the nozzle size
(Hypro Flat Fan 110° nozzle) and control box setting needed to maintain the correct flow rate. For example, to achieve a
flow rate of 1.50 litres/min will require a single Light Blue nozzle and the control box set at 6.
NB. This table is intended as a guide only. These optimum rates can be affected by a poor power supply, an
overlong power supply cable or delivery tube, a kinked or dirty delivery tube and dirty nozzles. You should
always check the flow rate yourself.
* LP nozzles are available on request (from Selmech Supplies)

MiniFlow S Applicator
Calibration
for forage harvesters - using two nozzles
CALCULATING THE FLOW RATE REQUIRED
Measure the time taken to fill a trailer or make a bale. Only include actual pick-up time, not time taken turning, etc.
Calculate the flow rate required as follows:
1. Harvest rate (tonnes/min) = weight of grass (tonnes)
time to fill trailer or make bale (mins)
2. Flow rate (litres/min) = harvest rate (tonnes/min) x required application rate (litres/tonne)
CHOOSING THE CORRECT NOZZLES AND CONTROL BOX SETTING
Choose the flow rate in the table below that is closest to the flow rate determined above. Then read off the nozzle size
(Hypro Flat Fan 110° nozzle) and control box setting needed to maintain the correct flow rate. For example, to achieve a
flow rate of 1.5 litres/min will require 2 Brown jets and the control box set at 8.
NB. This table is intended as a guide only. These optimum rates can be affected by a poor power supply, an
overlong power supply cable or delivery tube, a kinked or dirty delivery tube and dirty nozzles. You should
always check the flow rate yourself.

MiniFlow MB Applicator
Calibration
for mini haylage balers – using 1 nozzle
CALCULATING THE FLOW RATE REQUIRED
Find out the average time it takes to make a single bale (pick-up time only) and the average bale weight. Assuming an
application rate of 6 litres/tonne (eg DA Ecobale for mini-bales) use the time and bale weight to determine the flow
rate (litres/min) required from Table 1. For example, if a 50 kg bale takes 1 min to make, a flow rate of 0.30 litres/min will
be required.
CHOOSING THE CORRECT NOZZLES AND CONTROL BOX SETTING
Choose the flow rate in table 2 that is closest to the flow rate determined above. Then read off the nozzle size (TeeJet Fan
nozzles) and control box setting needed to maintain the correct flow rate. For example, to achieve a flow rate of 0.3
litres/min will a single yellow nozzle and the control box set at 5.
NB. This table is intended as a guide only. These optimum rates can be affected by a poor power supply, an
overlong power supply cable or delivery tube, a kinked or dirty delivery tube and dirty nozzles. You should
always check the flow rate yourself.
