Assembly and Disassembly
The dosing pumps are usually supplied already assembled. For greater clarity, you can consult the
attachment at the bottom of the manual which illustrates an enlarged view of the pump, and all the
details with its nomenclature, so that you can have a complete picture of the pump components. These
drawings are however indispensable if you have to identify malfunctioning or defective parts. Other
designs, related to the hydraulic parts (pump head and valves) are shown for the same purpose, in the
appendix.
For the eventual dismantling of the pump or before starting work on it:
•Make sure that it is turned off electrically (both polarities) by disconnecting the connection cables
from the contact points of the network through the opening of a phase switch with a minimum contact
gap of 3 mm (Fig. 6).
•In an appropriate manner, carefully dispose of any remaining pressure from the pump body and from
the injection tube.
•Remove all liquid present from the pump body, then proceed by disassembling and reassembling the
pump body, by unscrewing and screwing the four screws (tightening torque: 180 to 200 N * cm).
This last point requires special attention, so please refer to the drawings in Annex 1 and the chapter
"RISKS" before starting any operation.
Operating principle
The operation of the dosing pump is provided by a membrane in PTFE (Teflon ®) mounted on the piston
of an electromagnet. When the piston of the electromagnet is attracted, a pressure is produced in the
pump body with an ejection of liquid from the discharge valve. Once the electric impulse is over a spring
returns the piston to its initial position with a recall of liquid through the suction valve. Given the
simplicity of operation the pump does not need lubrication and requires very little maintenance. The
materials used for the construction of the pump make it suitable for the dosage of chemically aggressive
liquids. The dosing pump is designed for capacities ranging from 1 to 30 l / h and pressures of 4 to 20
bar depending on the model.

Installation
Introduction
This section describes the steps for installing the pump, the pipes, and the electrical wiring. Read these
instructions carefully before beginning any activity.
Follow these guidelines when installing the pump.
•Ensure that the pump and all related equipment is turned off before starting work.
•If you encounter abnormalities or warning signals, stop immediately. Only start work again when you are
absolutely sure that you have removed the cause of the problem.
•Do not install the pump in hazardous locations or in areas at risk of fire or explosion.
•Avoid electrical hazards and fluid leakage. Never use a damaged or defective pump.
Pump installation
Install the pump away from heat sources and in a dry place at a maximum ambient temperature of 40 ° C.
The minimum temperature, not lower however than 0 ° C, depends on the type of liquid to be metered, which
must always remain in a liquid state. To fasten the pump use the supplied screw anchors, or those most
suited to the support type chosen.
The pump can be installed either above or below the liquid level in the tank. Usually in the case of
installation above the tank, limit the suction height to within 1.5 metres of the liquid level. (see fig. 2a). For
liquids that generate aggressive vapours, do not install the pump into direct contact with the fumes and
adopt the necessary precautions to prevent early deterioration of the equipment.
In the case of installation below, i.e. with the pump positioned below the liquid level of the tank (Fig. 2b),
siphoning may occur. Periodically check the functionality of the injection valve, as excessive wear may lead
to the additive falling into the plant even with the pump turned off. If the problem persists, fit a back pressure
valve C suitably calibrated between the metering pump and the injection point as shown in Fig. 2b
Fig 2a. Fig 2b.

Electrical connection
Comply with the rules in force in the various countries with respect to the electrical installation. If the power
cable is devoid of a plug, the equipment must be connected to the mains supply via a double pole isolator
switch with a minimum distance between contacts of 3 mm. Before accessing any of the connection devices,
all supply circuits must be interrupted (Fig. 6).
Fig 3. - Electrical Connection
Hydraulic Connection
The flow connection will always remain in the upper part of the pump from where the tube goes to the
system to be treated. The suction fitting therefore will always be in the lower part of the pump, where the
tube with the filter will be mounted that goes to the container of the liquid to be metered.
1. Remove the seal on the nut (2)
2. Insert the pipe through nut (2) and the bushing (3)
3. Push the end of the tube (1) on the conical spout
of the nozzle (4)
4. Pull the nozzle (4) on the connector (5)

To prime the pump, connect the discharge tubing and follow the sequence shown in Figure 5.
•unscrew the bleeding knob, with the pump running,
•keep the bleed valve B open until all the air contained in the tube and in the pump body comes out,
•close the bleed valve.
If you are experiencing difficulty in priming the pump, then with a syringe withdraw the additive from the
bleed nipple reducing the number of impulses delivered by the device.

Both on the flow pipe and the suction pipe avoid excessive curves in order to prevent bottlenecks in the pipe
itself. In the point most suitable for the injection of the product to be dispensed, apply a 3/8" fitting or a ½"
female gas thread on the conduct of the plant to be treated. This fitting is not supplied. Screw the injection
valve to the "gasket fitting" using PTFE tape, see Fig 7. Connect the tube to the conical injection valve and
secure it with the locking ring (4). The injection valve is also a non-return valve.

Priming Function
In order to facilitate the priming the pump is equipped with PRIMING function. It’s recommended to open the
bleed air by-pass on pump head (for pumps with it) during priming. The air bleed nipple must always be
connected with the return hose to the suction tank.
The activation of this function can occur at any operating menu in the following way:
•Press and hold START/STOP button
•After about 3 seconds the pump starts delivering injections at the priming frequency of 150 imp/min, as
long as the operator does not release the START / STOP button. When you press the button the following
screen appears on the display:
•Once you release the button, the pump stops 10 sec. countdown starts. At the end the pump switches
back to the previous operating mode, in stand-by condition. Pressing the START / STOP button the pump
goes in running mode.

Page 13 of 35
Metering Pumps
Operating and Maintenance Instructions
www.empirepumps.com
•During the countdown pressing and holding down START/STOP the pump starts to give injections to
reach the right dosing condition to existing system pressure. We recommend that you use this procedure to
return the pump in optimal working condition especially if it operates at any proportional mode. During this
phase, you should close of the bleed valve on the pump body. Once you release the button, the pump will
return to stand-by mode.
•The PRIMING function can be utilized when the pump PASSCODE is activated. To do this press and
hold the START/STOP button, after 3 seconds the pump starts injecting at the priming frequency (150
strokes/min) until you release the START/STOP button. At the end of the sequence the pump will go back to
the previous mode. You will need to enter the password that you have previously used to get access the
different menus.
Special Warnings for the Metering of Sulphuric Acid (max. 50%)
In this case it is essential to bear in mind the following:
•replace the transparent PVC suction hose with a semi-rigid polyethylene delivery tube.
•remove in advance all the water present in the pump body, in fact if this is mixed with the sulphuric acid it
generates a strong concentration of gas resulting in the overheating of the area causing damage to the
valves and the pump body.
If the equipment is not attached to the system you can carry out this operation, by activating the pump for a
few seconds (15 -30) holding it upside down with no tubes connected to the fittings, if that is not possible
then disassemble and reassemble the pump body (Fig .10), via the four fixing screws.

For accurate metering, in the eOne and MF Plus models we have implemented the option to automatically or
manually set the actual flow rate for each injection. The following describes the practices that must be
observed for "AUTOMATIC" calibration:
Injection Calibration Procedure
•Fill a graduated cylinder with the additive to be dosed by the pump and immerse the suction tube in it.
•Connect the delivery pipe of the metering pump to the plant to be treated.
•From the "SETTINGS" menu select the function "FLOW CAPACITY" and select the "AUTOMATIC" mode
•Press the DOWN ARROW button to proceed to the priming of the metering pump which will begin to emit
injections, until the pump body and the two suction and discharge pipes are full.
•Once finished priming press the DOWN ARROW button.
•Select the frequency of calibration procedure by press RIGHT AND LEFT ARROW buttons (standard
value is 150 imp/min.).
•Press DOWN ARROW button. The pump will run for one minute.
•Once the injections are finished the metering pump will have suctioned a certain amount of additive
whose quantity can be calculated by means of the scale on the cylinder.
•The amount of suctioned fluid, for example: 110 ml, should be set on the display and via the ARROW
DOWN button the selected value will be confirmed.
•The logic of the pump will run the following operation:
value of additive suctioned / number of impulses delivered = flow rate of each injection (110 / 150 = 0.73)
•the factory-set value of 0.45 ml will become 0.73 ml.
Operational Functions of the Multifunction Pump
In order to facilitate the consultation of this manual, the configuration with the function described is shown in
the subsection titles.
Manual
This configuration is present in all versions. The metering pump operates at a frequency predetermined by
the user within the following range:
•0 to 300 impulses / minute (depending on the maximum flow)
•0 to 900 impulses / hour

Proportional 1XN (VFT, MF, VFT- T, MF -T)
The pump is provided with a connector for connection to an external water meter which can provide a series
of contacts proportional to the amount of liquid that must be treated. A flashing dot on the display shows the
input impulse from the meter. For each contact received, the pump delivers a series of injections equal to the
N value set by the operator. Any contacts that come from the meter to the pump, while it is already delivering
the N series of injections, are ignored.
Proportional 1XN (M) (VFT, MF, VFT -T, MF -T)
Unlike the previous mode, in this one the pump stores any received impulses in the memory while it is
delivering injections. Depending on the time interval between impulses coming from the meter, the pump
automatically adjusts the frequency of the injections. If the injections accumulated and still to be dispensed,
exceed the value "4 × N", the pump will go into alarm (if this alarm has been enabled) and stop the metering.
The display shows dynamically the number of injections that must be provided.
Proportional 1:N (VFT, MF, VFT-T, MF- T)
The pump is provided with a connector for connection to an external water meter which can provide a series
of contacts proportional to the amount of liquid that must be treated. Every N contacts received by the meter,
the pump delivers an injection. The display shows the number of contacts received up to the set value. At
the delivery of the impulse the display resets and begins the next count.
Proportional ml x imp (VFT- S, MF, VFT- S-T, MF-T)
The pump is provided with a connector for connection to an external water meter which can provide a series
of contacts proportional to the amount of liquid that must be treated. For each contact, received from the
meter, the pump delivers a number of injections directly proportional to the set value in "ml" (millilitres)
requested by the user. The display shows in a dynamic manner the amount dosed in "ml".
Proportional l x imp (VFT-S, MF, VFT-S -T, MF- T)
As for the previous mode with the difference being that displayed in litres.
Proportional ml x m3 (VFT- S, MF, VFT- S-T, MF-T)
For those who need a ml x m3 metering a specific function has been provided: by setting the required
parameters in the programming menu, the electronic system performs the necessary calculations and
determines the type of intervention required to effect the pump. The parameters that must be defined are the
following:
L / I METER Sets the litres per impulse that are delivered by the meter used in the system, the
expected types are as follows:
0.1 –0.15 –0.20 –0.25 –0.30 –0.35 –0.40 –0.45 –0.50 –0.55 –0.60 –0.65 –0.70 –0.75

% SOLUTION Generally the additive to be dosed by the pump is part of an aqueous solution in a
specified percentage. Set this value using the special arrow keys of the keyboard:1–100%
ml x m SET3 set the value in ml x m3 which must be guaranteed in the plant. The permissible range is
as follows: 0.1 –50.000 ml x m3
Proportional ppm (VFT - S, MF, VFT-S-T, MF-T)
For those who need a Parts per Million metering the PPM function has been provided: by setting the
required parameters in the programming menu, the electronic system performs the necessary calculations
and determines the type of intervention required to effect the pump. The parameters that must be defined
are the following:

% SOLUTION In many cases the additive to be dosed by the pump is part of an aqueous solution in a
specified percentage. Set this value using the special arrow keys of the keyboard: 1-100%
PPM SET Set the value in p.p.m. (Parts Per Million) that the plant must guarantee. The permissible
range is as follows: 0.1 –50.000 ppm
Proportional mA (VFT- S, MF, VFT-S-T, MF-T)
The pump is equipped with a current input. It receives a signal that is between 0 and 20 mA and delivers a
series of injections proportional to the signal received.
The parameters to set are the following:
Setting mA (1) SET 1:
mA value at the set point 1, through the definition of SET 1 we establish the value
in mA from which we want to start the metering. Default Value - 4.0 mA.
Setting mA (2) SET 2:
mA value at the set point 2, through the definition of SET 2 we establish the value
in mA from which we want to start the metering. Default Value - 20.00 mA.
Impulses/minute (1) SET 1:
The pump automatically changes the frequency of injections between the two set
points previously set (SET1 - SET2). The user has the option to define the number
of impulses per minute, corresponding to the value in mA set in SET1: Default
Value 0 imp/min.
Impulses/minute (2) SET 2:
The user can define the number of impulses per minute corresponding to
the maximum metering peak: the largest selectable value must be greater than
that set on the SET1 but may not go beyond the maximum frequency of impulses
per minute that can be delivered by the pump.

Under mA (1) SET 1:
In relation to the system requirements, the pump allows you to determine whether
to continue or terminate the metering when the measurement takes on a current
value below the set point 1 (SET1).
Above mA (2) SET 2:
In relation to the system requirements, you can define whether to continue
or terminate the metering when the measurement has a current value above the
set point 2 (SET2).
