BluePump Spare Parts
The BluePump is very reliable and therefore it does not need spare parts all the time. We advise a service visit every year by a qualified local Pump Mechanic to check on all nuts & Bolts and the Pumping System.
Nevertheless, it is good to know that you always can get a quick service for any part that you may need.
Spares are available from your local country dealer, or from a BluePump NGO partner, or directly from Boode B.V. We are known for a quick end quality service because we know that pumps need to work, every day.
On each BluePump in the field, you find our mobile nr. +31 6 236 686 15 that you can SMS or call in case you need urgent assistance or spare parts. Actually, we hardly receive any calls, which indicates that most BluePumps are functioning all over Africa.
On the front side of the BluePump you will find in the cap 4 small holes, here you can attach with rivets your own project info or any message or advertisement that you may like. You can order an aluminum plate with 4 holes and rivets for that purpose when you buy your BluePump.
In the technical drawing below you find a list of all current parts of the BluePump model 2018. In case you have an older type, don't worry, all new parts are compatible with the older parts.
From time to time we improve BluePump parts or add new parts, based on feedback from the field. Over the last years some of the main improvements are:
- #1 The Bottom Sump Pipe; we made this a PVC pipe with a screen, the purpose of the screen is to deal with the silt that can settle on the bottom of the borehole casing in the space of the borehole sump pipe. The space between the BluePump pipes and the borehole sump pipe is not so much, so when too much silt builds up, without this extra sump pipe, the BluePump pipes can be difficult to take out when needed.
- #3 The Conical Seat Socket; the conical seat is now pre-glued inside a special longer socket, which is pre-glued to a screen pipe.
- #5 The PVC pipe; we reduced the length of the PVC pipes, from 3m to 2m. This was done to make the total pipe structure stronger. Hanging PVC pipes are flexible and can stretch during pumping, which can cause cracks. By reducing the length, combined with strongly glued sockets every 2m, the stretching during pumping is considerably reduced.
- #8 Ertalite Foot Valve; this replaces the stainless steel footvalve. It is screwed inside the bottom of the stainless steel cylinder #12, however, when stainless steel is screwed into stainless steel, the threading can get stuck when there is sand or silt in between. With Ertalite, this is not possible.
- #15 The piston stabilizer; The purpose of this is to keep the piston centered and at the same time, offer additional pressure. It is made from high-quality material that is normally used to make the shaft of a motorboat watertight.
- #22 The rods: Originally, we started with traditional 10mm rods of 3m long, but we found that this gave too many vibrations during pumping, especially in deep boreholes, which could ultimately lead to broken rods. Therefore we reduced the length to 2m and increased the diameter of the rods to 12mm. Also, initially we used plain rods with roled on threading, but we changed that to rods that have threading from the top to the bottom. The obvious advantage is that you can cut the rods anywhere and always have a connection. In the rare case a rod breaks for whatever reason, you do not need to find a new rod, you just connect it again.
- #25 The rod centralizer; Centralizers can wear out in deep boreholes due to the fact that deep boreholes are not straight. The early models up to 2009 of the BluePump had a white centralizer that was in fact too strong, so with time, it could damage the inside of the PVC pipes with time in curved boreholes. This new one has the color blue and is made from a material that has a slightly lower hardness than PVC, so it can not damage the PVC pipe. The advantage of this material over rubber is that it has a very low glide resistance and does not wear out that fast as rubber, so it last much longer. There are 2 on each rod that fit into each other. If one side wears out, the centralizer can be turned around 90 degrees to make is again a complete round centralizer. Another advantage of this new blue centralizer is that this special material is lighter than water, so when small parts may come off with time, they do NOT sink down as is the case with rubber centralizers, which can get stuck in the pumping system of the pump. Instead, these small parts will flow upwards and flow out of the pump with the pumped water.
- #27 Centralizer stabilizer; This is a strong, flexible rubber disc that is mounted on top of the centralizer. The purpose is to stabilize the flow of water upward and downward, while it also helps a bit with the pumping as an additional valve. This will increase the water output and protect the pump system from a hydraulic shock.
- #29 Base Plate; The old model consisted of only 4 holes on the corners like most handpumps have, but we found that in deep boreholes that a strong connection of the metal box with the concrete is very important, so we have now 6 anchor bolts. Older models also had 2 parts made from POM but these are now replaced by 1 part only, made from galvanized iron. It has 4 little 13mm diameter holes inside that fit the construction holes of the Afridev and India MK pumps. This makes replacement of these pumps with the BluePump easy and fast. The Base Plate also serves as a mold to position the 6 anchor bolts in the concrete pedestal.
- #30 Anchor Bolts; The traditional anchor bolt comes with a hook. We added a new type that has a "bayonet" curve to secure it in the concrete.
- #34 The Spout; The new spout is now from Stainless Steel 304; this was needed because we found that is some situations the groundwater is very aggressive and the spout started to rust in these extreme conditions.
- #41 The cap; The new cap is made from stainless steel 304, because we found that similar to the #34 Spout, in some cases very aggressive water could make the cap to rust.
- #50 T-piece; Adjustable T-piece with #49 counterweight. This replaces the long fixed handle from the previous models.
- #51 Cover plate; We added this plate to cover the opening of the borehole on the #29 Base plate during the time that is needed for the concrete to dry out. This is needed to avoid that dirt etc. comes in the borehole.
- #59 Anchor connecting nut M16; This was added to connect the new "bayonet" anchor bolts together to make it longer and to add #60 to it to make the anchor construction stronger. This was needed for very deep boreholes because we found that the high stress on the anchor bolts could give problems with the concrete.
- #60 Anchor strip; This was added to the anchor system to get a better grip for the anchor bolts in the concrete.
- #61 Bolt M12; This bolt was added to secure the cover plate on the base plate.
- #62 Pipe Centralizer; There is always some space between these PVC pipes with outside diameter of 80mm and the borehole casing, that is often 41/2" with an inside diameter of about 115mm. Especially in the case of a "hanging pipes" the PVC pipes can move laterally and vertically due to pumping, which can cause fatigue in the pipes and ultimately may cause minor cracks in the PVC. These special centralizers avoid that and improve the longevity of the system.
- #63 Plug Bottom Support; With this plug, you can change the "Open" Bottom Support PVC pipes into "Closed" sections of each 2m long. This means that these closed pipes will float in the borehole, and therefore reduce the pressure on the #10 Bottom Plug, and avoid that the total column of PVC pipes will press too much on the bottom plug of the borehole casing. The floating of the Bottom Support pipes will also make the installation in deep boreholes easier because as soon as these pipes will be at the water level in the pump, they will reduce the total load of the pipes. Remember, in the Bottom Support section that is no flow of water needed; the water enters in the pump through the #2 Screen of the piston pipe.
- #64 Floater for rods; This is an option for very deep boreholes to make the pumping considerably lighter by about 50%. These floaters are simply put over the rods and secure with a #Locknut. During pumping, each time the total column of water needs to be lifted. They replace the water by air, therefore the pumping at 90m deep will feel the same as 50m deep. This also improves the longevity of the pump system and bearings.
- #65 T-piece extra wide; This makes pumping with 2 persons easier because they can stand side by side, in the case of a deep installation.
- #66 Water Hose connection; This makes the water coming out of the T-piece in a more concentrated flow, and also enables to connect a standard water hose of 25mm diameter to the pump. With a hose, it is not necessary to place a jerry can or container directly below the spout and can also be used to irrigate a small vegetable garden next to the pump.
- #67 T-piece protection; This is a strong rubber disc that can be pushed over the top part of the rods to protect the inside of the rising main from dust or parts falling in.
