1 NIRA 67 Playground pump
Nira 67 Playground pump is intended for children’s playgrounds. The pump is designed to be connected to a
pipeline and therefore cannot be used for pumping water from ordinary water wells. This document gives
instructions for operating and maintaining the device. Please familiarize yourself with these instructions
before using the device. Use the device only as described and for the specified applications. Store these
instructions in an appropriate way, making sure that the instructions are available to all possible users
throughout the life of the device.
To avoid injury, follow the instructions given in this document.

2 Introduction
2.1 Inspection upon delivery
Before the device is taken into use, check that the packaging is intact and that it has not been damaged
during transportation. Please notify the transport company and the supplier of any transit damage within two
(2) days of receiving the delivery.
Ensure that the delivery contains all the parts detailed in the delivery note. If there is anything missing from
the delivery consignment, please contact the supplier immediately.
2.2 Before use
NIRA 67 Playground pump is intended to be used in children’s playgrounds and other places where the
pump can be connected to a water pipe line instead of water wells. NIRA 67 Playground pump cannot be
used for pumping water from water wells since it has no pumping mechanism.
If the pump head is too high, it can be adjusted by sliding the pump body through the base plate approx. 50
cm. Height adjustment inquires requires enough free space under the base plate.
A steady slab is needed for installation. The base plate must be mounted on the slab. Under the slab there
must be enough free space for adjusting the pump head and for installing the valve to the pipeline. Use
rubber hose and make sure that there is few meters of hose rolled in the stand (Figure 3). This way the
possible pressure changes won’t affect the operation of the pump.

Also a hosepipe with a hose clamp and a hose pipe coupling with ¾” thread is needed (Figure 4).
Note following important issues:
Pressure 4-6 bars; the higher the pressure, the higher the water consumption. Pressure has an
impact on the closing of the valve. Pressure shock absorber is available as an accessory. The use of
the absorber is recommended since it reduces hydraulic impacts o the pipe line.
For the connection to the water mains, contact your plumber and adhere to EN1717- Protection
against pollution in water installations and general requirements of the devices to prevent pollution
by backflow.
Priming water must be added before use. Remove the plug (Figure (21)) and fill in approx. 1 liter f
water.
While pump is in use there must be water in it to lubricate the mechanism. The pipe water
must be clean.
The pump may exert the pipeline and its joints. Use the pressure shock absorber (optional).
Do not use the pump without priming water as the mechanism can get damaged if dry pump is
used.
The pumpshould not get frozen, while priming water is in the pump. The operating
temperature is between +2°…+50° C.
Shut off the closing valve of the pipeline when the pump is not in use.
A small amount of water remains in the pump. The pump should be flushed daily before use.
Use the pump according to its intended use.
3 Using the pump
3.1 Installation
As a standard the package contains following items:
Base plate (1 pc)
Pump body (1pc) with installed handle and valve
The stand is available as a accessory.
Tools needed for the installation:
13 mm spanner or adjustable spanner (1 pc)
10 mm hex key (Allen key)

Figure 5: Base plate
Figure 6: Installing the hose coupling
1. Install the base plate on the desired height on the pump body (Figure 5)
2. Attach the hose coupling to the valve and install the hose pipe on the hose coupling with a hose clamp
(Figure 6).
3.2 Taking the pump out of use
If the temperature goes below the operating temperature (+2 °…+50°C) any time of the day, the pump must
be disconnected and dumped.
1. Close the water tab and remove the hose
2. Remove the plug on top of the cover (Figure 1(21)).
3. Move the handle on the uppermost position.
4. Turn the pump upside down so that the water can drain from the pump through the opening.
5. If the stand is used, place the cover in place (Figure 2 (4))
6. Store the pump in warm and dry place.
Ø 10,5 mm
190mm
3. Install the base plate on the slab. Hole pattern is 4x190 mm and
diameter 10,5 mm (Figure 5).
4. Add priming water (1 liter) before use. Remove plug (Figure 1
(21)) on top of the pump. Fasten the plug.
5. Water has to be added if the water inside the pump has drained.
Usually no water has to be added as long as the hose is filled with
water and is connected to the pump.

4 Maintenance and repair
4.1 Regular inspection
NIRA Playground pump is a playground equipment. According to the EN 1176 regular inspections have to be
made to ensure safe operation. Weekly inspections are recommended.
If the screw (Figure 1(23)) comes loose do not try to tighten it. The screw must be removed
and thread locker (e.g. Locktite-Threadlocker) must be added to the thread.
Use only new locking washers (Figure 1 (22)). Install the handle again with the washers and tighten the
screw with approx. 40Nm torque.
4.2 Maintenance
NIRA playground pumps do not need periodical service. Water impurities are the most common reason for
malfunction in the valve system. In this case the valve needs to be cleaned. When the pump opened and
cleaned, change the O-rings in valve at the same time. Intensive use may cause the spring (Figure 1 (19)) to
wear out and break.
4.3 Detaching the cover
The cover is fastened to the pump with hexagonal screws (6 short and 1 long).
Figure 7: Detaching the cover
1. Unscrew the screws (5 pc.)(Figure 7(1))
and remove the cover.
2. Remove the screw (2)(Figure 7). Notice
that the sand blockage (marked with red
circle) won’t come out but you are now able to
unscrew the screw (3).
3. Assemble the pump in reverse order. Make
sure that the seal is properly in place.
