USE AND MAINTENANCE INSTRUCTIONS
FOR 35.014 HAND WINGS PUMPS
In continuous production since 1919, the 35.014 pump is one of the world’s original type of semi-rotary hand
wing pump.
The pumps are operated by the movement of the handle. This handle causes the shaft and the wings, which is fitted
with
flap valves, to semi-rotate within the pump. Also enclosed in the body of the pump is the suction divider, fitted with
flaps. Two lugs facilitate the mounting of the pump to a wall or similar structure.

If using aggressive fluids, toxic or harmful to health, install appropriate protections to contain and collect the product in
order to prevent the danger of pollution, contamination, injury. Do not use in areas at risk of explosion. Place warning
signs for chemical fluids in proximity of the working area. Ensure that the area has adequate aspiration systems.
Never leave 35.014 pump unattended. If left unattended, unauthorized personnel could get in contact with
dangerous fluids.
The work area should be clean and well lit.
Before returning the pump to the manufacturer for review, make sure to empty and wash the pump to prevent loss of
fluid during transport.
Traces of grease on the lever or on the operator’s hands must be removed before any use.
The operator should not wear large clothes, bracelets, necklaces and must tie up long hair.
Make sure there is someone else than just the operator when 35.014 pump is working in order to help in the event
of an accident. If you are pumping hot fluids, avoid contact with the parts that are hot to avoid skin burning.
Some pump models have aluminium and zinc plated parts, these models are not suitable for pumping chlorinated
solvents and halogenated (for example: Trichloroethane and Methylene Chloride) as they can create high risk of
explosion.

The standard pumps are not suitable for edible liquids (water, wine, milk, oil, juice, etc.)., otherwise they are indicated
with the abbreviation AT (non-toxic). In case of repair or maintenance of these machines, during reassembly will be
indispensable to use specific lubricants as ecological oils etc...
4 –GUARANTEE

The warranty runs for 24 (twenty four) months from the despatch date.
Any defects, faults or malfunctions should be reported to the manufacturer. within 8 days of purchase. The repair or
replacement under warranty will be made only inside the manufacturer. and 35.014 pump must be returned there.
the manufacturer. does not make any kind of work outside it’s firm.
In case of repair or replacement, the warranty will not be extended.
In the event not functioning of 35.014 pump caused by defects not related to the the manufacturer. product, but due
to user's mistakes , the manufacturer reserves the right to charge to customer the cost of parts and repairing work.
5 –INSTALLATION OF 35.014 PUMP
Please call the manufacturer if you have any questions.
Check the material and its seals, check the compatibility with the operating liquid and then proceed with the
installation.
Make also sure you have accessories (if they come with the pump), assembly tools, appropriate seals and security
protections.
Make sure the pump is installed in a position where it’s accessible for working and maintenance.
If the pump is made of conductive material please pay attention to static electricity to prevent the risk of explosion or
fire in case of use of flammable materials.
Never modify any part of the machine during installation. Install 35.014 pump in the upright position following
the direction harrows on it and pay attention to the direction of flow. Please verify the positioning also reading the
wards written on it that do not have to be upside down.
For connections using only thread type made of compatible material with the fluid and with the material (for example:
with a stainless steel pump the joint must be of stainless steel).
During assembly sealing fillets with appropriate sealing systems. Weak screwdriving may lead to leak of liquid during
working operations, while strong ones may damage the female thread with cracks or breaks. In case of use of flexible
hoses fitted without thread, lock it with appropriate clamps.
The delivery hose and suction tube, connected to the IN and OUT inlets of 35.014 pump should never be of
smaller diameter than the attack of the pump and should not be made of material compatible with the operating liquid.
Strainer, foot valves, curved hose connection and other components has to be properly installed to prevent pressure
drop.
For viscous fluids use pipe with a larger diameter.
In case of usage of threads, it will be necessary to interpose products that prevent any leakage: PTFE (Teflon) tape or
in
liquid or fillets paste.
In the case of mounting 35.014 pump on barrels, suction tube is inserted in a hole with a diameter bigger than 2",
at the same time unscrew the smaller cap present on the barrel to avoid problems due to the pressure caused by the
aspiration of the pump.
In case of use of 35.014 pump on a barrels, the suction tube (which is lowered into the barrel) must have the ends
obliquely cut to prevent sticking on the bottom caused by the vacuum exerted by the pump in operation.
Before starting to pump, tighten and check all the joints between 35.014 pump, the suction tube and delivery

Never direct the delivery hose to itself or to any other parts of the pump or the pumping unit.
Make sure that there are not electrical equipment around operating area.
Do not place either fittings or hoses under strong physical shocks. Damaged components have to be replaced because
represent danger.
Prevent hoses from being pinched, bent or trampled. If the pump operates with dangerous liquids constantly check that
the hoses are not worn or in poor condition, then empty the pump and replace it. If the machine has been purchased to
treat explosive substances, make sure that the pump, the suction tube, the connections and all other particular
are anti-spark to prevent to trigger a spark.
When water is used and the pump is placed outside pay attention to winter temperatures as it can fall below zero. Avoid
leaving fluid into the pump as water, when iced, increases it’s volume and could break the body of the pump. For this
kind of use it is highly recommended to empty the pump at the end of each operation.
If the pump body is made of iron or iron bland material, in contact with water can form an oxide film which create
problems sliding on the internal parts of the pump. In this case empty each time the pump and dry it in order to avoid
formation of rust.
In conclusion, we provide a brief summary, as written above, for the installation and use for 35.014 hand
pumps.
1. Make sure the pump is installed in a position where it is accessible for working and maintenance.
2. Fit suitable hose. the manufacturer. recommend, when flexible hoses are required, the use of spiral reinforced
hoses for suction and delivery. Non reinforced tube on the suction side could collapse or kink during operation
and could be badly affecting the pump’s performance.
3. To obtain a good air tight connection, with PVC hoses, between the hose and the pump, soften the hose ends in
boiling water before fitting.
4. Use good quality hose clips.
5. If possible, mount the pump so that the discharge port is at least 30 cm. below the hose's discharge point. This
will ensure positive valve operation.
6. Make sure that there is enough room to obtain the correct movement of the handle.
7. The flow through the pump is in the direction of the arrow on the pump cover.
8. Move the handle of a full stroke. Short quick strokes will result in loss of output.
9. Before any output is obtained will be necessary to make few initial trial strokes. The liquid has to be drawn up
from the suction tube.
10. No routine maintenance is required. However the periodic use of the pump will help ensure a freely valves
operation, that there are not leakages from the diaphragm and that the pump operates when required.
11. When spare parts are required, contact the manufacturer. and provide a correct description of the part, the model
and the quantity required.
12. When re-assembly the pump make sure that the valves seats and faces are clean and that the valves can move
freely.
13. When storage is necessary for a long time empty the pump and keep it in a dry place.
6 - MAINTENANCE
For your own safety adopt safety devices (glasses, gloves, aprons, shoes etc) before working with the pump. Before any
maintenance or repair need to completely discharge the product.
Maintenance or replacement has to be done by qualified personnel only.
To disassembly follow the assembly steps in reverse order.
Also remove hose connection and any strainer and other accessories.
After those steps place 35.014 pump on a work bench, in the case of simple maintenance, check lever's
movement and introduce lubricant fluid.
In case of broken internal parts, the central and the lateral covers can be removed and new parts inserted. Please read
Chapter 10 of this MUM “Technical data”.
When spare parts are required consult the manufacturer. and quote correct description of parts, pump model and quantity
required.
If you do not follow the guidelines above there could be danger for operator’s safety and for the environment. Those
kind of accidents will not be attributable to the manufacturer.

It is not recommended to try to self repair or replace parts, it is best to return the pump to the manufacturer who has all
the equipment for the intervention, and can execute a final test that allows you to verify the success of the operation.
If kept in stock for a long time lubricate internal parts, ensure that the pumps are protected from humidity and rain with
temperatures between 10° and 45° C and with a humidity under 85%.
Keep out of the reach of children.
the pump should be lubricated before reassembly and the operator should check the tightness of all its parts.
7 –REMOVE FROM SERVICE AND USE
Protect with appropriate safety clothing. Drain the pump from any remaining fluid.
If the machine has pumped corrosive liquids (acids or dangerous) washed with inert fluid.
Disassembly the accessories. Follow the same instructions as in chapter 6 "Maintenance".
8 –DISPOSAL AND SCRAPPING
The pump is made of non-dangerous materials, in any case at the end of the life cycle or demolition you must
empty the pump from any residual liquid.
In the case of use of hazardous or toxic or harmful to health fluids, clean with water the pump and components to
prevent injury or harm to humans and to the environment.
If the appliance is to be scrapped, treat it as a special type of waste.
Dismantle it and divide materials for typology, then dispose them in accordance with law and regulations in the user’s
country.
9 –MAIN CHARACTERISTICS AND TECHNICAL SPECIFICATIONS
All technical data listed below are for standard 35.014 pumps.
These values are subject to change without notice, due to the constant research for innovation and improvement by the
manufacturer.
The following technical data, drawings, product names, text, etc.. are owned by the manufacturer any copying or
improper use is forbidden.
Any request may be submitted in writing to the manufacturer who will evaluate the possibility of granting such
permission.
The pump performance is referred to normal conditions of work: as process liquid is considered fresh water at
room temperature, the reference temperature is 20° C and humidity under 70%.
The data are calculated considering a pump without any accessory and free of pumping, this means that any device
mounted downstream or upstream of the pump can cause a pressure drop and perhaps a performance decrease.
Changing environmental conditions or quality of the fluid to be pumped, varies the performance.
Pay attention to the transfer of hot acids, because the degree of aggressiveness of many acids varies in function of
temperature.

10 –35.014 PUMP TECHNICAL DATA
35.014 hand pump is robust and easy to manufacture, it was designed to last without maintenance or special
assistance. These pump is operated by a left and right reciprocating motion achieved by a handle of wood on an iron
spike or a one piece metal handle of iron or aluminium.
Internally there is a "wing" fitted with two valves, at the lower half of the body there is a suction divider that has
further
two valves. Left and right motion of the handle causes the "wing" to wobble, causing alternate suction and discharge on
the two sides of the pump. The resulting flow of liquid is nearly constant with a slight drop at the end of each stroke.
This type of pump can give up to 7 metres of lift if a foot valve is fitted; this device is unnecessary when the lift is less
than 2 metres. Discharge pressure is up to 2.5 bar (say 37 lbs psi) depending on the size of the pump.
The following instructions of use will ensure the best performance from the pumps, prevent malfunctions, failures and
reduce maintenance interventions.

35.014 pumps are:
• Easy to use
• Double acting
• Self-priming
• Reciprocating action (from left to right to left)
• Priming-pressing
• Semi-rotary wing pumps
Hand pumps are operated by human power and therefore the flow-rate is proportional to the revolutions per minute
(RPM) given by the operator and to the diameter size.
The flow-rate is also influenced by
• Fluid viscosity
• Fluid temperature
• NPSH value
• Pipe diameter
• Distributed and concentrated pressure drops
Model Diameter
(inch) Flow rate (lt/min) Weight (Kg)
35.014 1’’ 30 6 Kg

For example: E2/B-be means
• E = 35.014 pump
• 2 = 1” counter flange diameter
• B = bronze body, stainless steel shaft and screw
• Be = VITON seals for fuel and solvents
35.014 pumps can be supplied without accessories, or as a part of a pumping unit.
Pumping unit does not provide foot valve, but it’s recommended their use to keep the circuit filled after pumping
operations.
If you are using a standard 35.014 version (GB), do not use with aggressive chemicals such as solvents, gasoline
etc.. The standard type works best with non-aggressive fluids: water, oil and diesel. Always pay attention to safety
standards.
In case of use of an 35.014 pump with VITON seals (BE type) operator has to pay attention and care as the
machine is risky and dangerous.
The standards refer to Chapter 3 of this MUM "Safety instructions".
All models have, on the back side of the body, two clamps useful for wall mounting.
the manufacturer. does not provide screws for these fittings.
When 35.014 pumps are part of a pumping unit for pumping oil from barrels, these clamps are not needed.
35.014 pump is individually packed and each box contains:
1. Hand pump
2. Hand lever
3. Counterflange (except the E00)
4. Counterflange seals
5. Screws for hand lever
6. Screws and bolts for counterflange
7. M.U.M. (Use and Maintenance Manual)
the manufacturer. does not supply standard spare parts kit.
35.014 pumping unit is individually packed and each box contains:
1. Above 1,2,3,4,5,6,7 step.
2. Rigid suction tube
3. Bung adaptor (2”)
4. Foot valve (optional)
5. Curved brass hose connection
6. Flexible delivery hose
7. Hose clamps
8. Anti drip spout
9. Manual nozze (optional)
10. Flow-meter (optional)
When receiving goods customer must check that the package contains the above listed parts.
Then proceed according to Section 5 of this MUM: remove the pump from the packaging, assemble the lever and fix it
with the screw and washer provided, assemble counter-flanges and flanges with sealing rings.
In case of mounting on barrel make sure that the hydraulic seal of all the assembled parts are guaranteed:
counterflanges,
suction tube, hose connection, manual nozzle, flow-meters etc..
In case of wall mounting, if you install flexible suction tubes, use only reinforced anti-collapsing types in order to
prevent crushing of the pipe due to vacuum created by the pump during operation.
The models 35.014 E00, E0, E1 and E2 have an internal system of valves with sealing and compression spring,
this allows the 35.014 to work also in oblique or horizontal positions. Pay attention in the case you mount the
pump inclined 180° would arise problems caused by the weight of the liquid that could charge on the valves and might
open them.
All other models of 35.014 pumps (E000, E3, E4, E5 and E7) have clapper type valves that work only for gravity
and therefore must be mounted vertically.
For a correct and complete pumping, act on the lever with reciprocating movement, about 45° to the right and 45° to
the
left.

Do not use excessive force to prevent damaging of internal parts, partial or incorrect use of the pump reduces the
flowrate
Q.
At the beginning the pump body and the pipes are empty and few cycles need to be made before liquid will flow out
from the delivery hose.
The flow will follow bottom-top direction, indicated by the arrow shown on the cover of the pump itself.
For each half-cycle corresponds delivery. At the end of the stroke the direction of rotation of the handle is reversed,
this
is "point 0" where the pump does not deliver.
The curve looks like this:
Attached here below you can find technical charts showing the overall dimensions, weights of the individual pumps,
flow-rate in liters/minute.
(To change the unit of measurement of the flow-rate from Litres/Minute to Cubic Meters/Hour multiply x 0,06. For
example: if a pump has a Q of 40 liters / min, multiplying by 0,06 you get 2.4 cubic meters per hour).
The sectional drawings here enclosed are needed to identify all internal and external components of the pump. This will
be useful for ordering spares parts as well.
