Performance range

Capacity: 72~20000m3/h.

Head:  6.8 ~ 186m

Instruction of pump type
For example    10SA(SAP)-6JA

10-The number obtained from the inlet diameter divided by 25(inlet diameter is 250mm)
SA(SAP)-Single-station double-suction centifigual pump with horizontal split

S: Single-stage double-suction centrifugal pump with horizontal split casing.
6-The number obtained from the pump specific speed divided by 10.
J-The rated speed is changed

A-Outer diameter of impeller is changed.

Structure
The pumps is horizontally mounted, the pump casing and pump cover are divided along the axis. the upper is the cover, the lower is casing, the inlet and the outlet are on the pump casing under the axis, and their centerline is perpendicular to the axis, the rotor elements will be removed without disturbing the inlet piping, the outlet piping and the motors, only dismantling the pump cover while inspection.The shaft seal is either packing seal or mechanical seal(single end surface non-banlancing type).
The direction of rotation
The rotation of the pump rotor is counter clockwise looking from the motor to the pump, i.e. the inlet is on the left and the outlet is on the right. The driving end may be moved to another one according to customers'requirements, meantime, the rotation,the direction of the inlet and the outlet are opposite to the above -mentioned.

Material of main parts
The medium-contacting parts are made of cast iron.
The material of impeller: May be cast steel /brass /according to customer’s requirements.

Features of the SAP pump

1. The rotor elements are propped up with two bearing points, so it is stable and low noise in operation.

2.Double-suction impeller itself can balance thrust.

3.The shaft with changeable sleeve is protected from wearing and has a long life.

4.When you dismantle the cover and put it to a secure place, the rotor elements will be removed for inspection.

5. It's unnecessary to dismantle the inlet piping and outlet piping while maintenance.

6.Thre are packing seal and mechanical seal in seal ways, customer may choose it according to the requirements.

7.Remained water in the inside of the pump can be completely drained, so the pump is not damaged by frost in cold places.

8. The pump uses rolling dearings, it runs for a long life, it is easy for maintenance.

The material of main parts of pump

Pump, motor and coupling, common bedplate will be supplied when inlet diameter is less than 200mm.

Q:How long should it take a mechanic to replace a water pump on a 96 dodge intrepid ES with a 3.5L engine? I was given a estimate of 6 hours does it really take that long? at 100.00 a hour I'm not sure my car is worth fixing
YES! It's driven by the timing belt so make sure they replace that too! edit: everything bill b said is true.....but he's thinking of the 2.7 motor. not the 3.5. Thank you. Your welcome. The labor rate in my shop is $95.00 an hour. Most all basic jobs are rated into a labor time data log by auto manufactuers and used world wide! These labor times stand up in a court of law!!! If it calls for 6.0 hours of labor, and you know I charge $95 an hour, that's $570 plus parts. Some shops charge less per hour and use cheap parts and leave bolts out and your constantly having problems. Some try to charge 8.0 hours for a 6.0 job just to rip you off. Some shops never worked on one and some shops are on there 3rd set of special 3.5 cam holders for doing water pumps and timing belts if you know what I mean!! Always get on the phone and shop around. Call the dealer and ask for the labor time for a particular job if you feel the need to.
Q:Water pump maintenance what should be maintained?
Bearings, seals, impellers - removing dirt
Q:What does 'MCL' Unit stands for water pump. How can convert this Meter head of the pump. For example : 50 MCL to ------- MTR HEAD. What is the formula?

Q:I had high-pitch noise coming from my engine; it was coming from the belt area. I change the belts but the noise is still happening. After doing some research, I noticed that the noise is coming from the Water pump bearings. I installed this water pump Last year and the warranty is expired on it. A friend told me that if a bearing goes bad on a Water pump, then I should flush the cooling system because it leaves metal shavings into the engine. Is this true? I already flushed my cooling system at the mechanic (he has a special machine) about 2 weeks ago. Is it necessary to do another flush because of bad Water Pump bearings?
well they do go bad but not very offen.. and really no need to flush if your going to replace it .. nothing to worry over
Q:2 different pulleys are in the way of the 2 remaining long bolts. at each end of the pump. tensioner did not need to be moved as belt is already off. Motor mount is 1/2 way removed and motor has dropped slightly gt; Am reading a jack must be placed under motor with wood via oil pan ( am hoping no other damage was done) Am told there is a certain device available to remove the pulleys? ... -Would appreciate anyone's info and advice on the remaining steps to this procedure on this make and model engine. as I have come into it obviously with it having begun the wrong way!! Thanks!!
to get the water pump out you need to remove the water pump pulley first it has four 10 mm bolts (I have seem them with 8 mm bolt with a large shoulder on them too ) you can break the bolts loose one of 2 ways 1) put a long screwdriver between the two of the bolt to hold the pulley in place while u break one loose then spin the pulley around rinse and repeat once there all loose u can turn them out by hand and pull off the pulley some time u have to give the pully a little tap to come off you shouldn't need to take off the motor mount unless u plan on chaging the serpintine belt ? be sure once you get the pump off you clean the block side of the surface really good with a scraper make sure u get all the old gasket off the block side so it will seal right when u install the new pump I also recommend a tube of ultra black rtv sealant and only black I have used blue silicone before on many occasion and it has failed me I only use black rtv plus it makes it a lot easier if you have to replace the pump in the future as it come off a little easyier hope this helps a little good luck may the car gods be with you also I would recommend doing a back flush with warm or hot water and using the old school green antifreeze either full or 50/50 mix Dexcool orange has a very well know issue of eating gaskets and putting engine into a vapor lock very costly to fix
Q:1997 Caravelle 1900BR3.0L HO Volvo PentaSX Cobra OutdriveI have a small leak coming from my raw water pump, it is not a continuous stream just a drop every now and then. The best I can tell it is coming from between the shaft and water pump housing. Is there just a small o-ring there? How can this be fixed?We're going to the lake for Memorial Day Weekend. Will I be alright with the small drip for over the weekend? Then I'll fix it when I can get the parts.
Well I don't know what mavrick is smoking but obviously he hasn't got a clue about a raw water pump on a volvo. He probably is on a sail boat. Here it is. There is a non replaceable seal on the shaft in the back of the pump.You have a 12 year old boat. Its time it went bad. The only way to repair it is to replace the pump. If you could get a seal from Volvo ( I will look it up in a minute) You would have to press the shaft out of the pump and this would more than likely end badly . You would end up replacing it anyway. So replace the pump , If it is just a small drip and the engine is not running hot you can run it but there is no telling when it will all of the sudden just disintegrate.
Q:How much would a water pump cost for a 1991 cadillac deville
Water pumps are cheap.. its the install time and or labor cost to do it that is pricey
Q:My truck turned off by itself and a bunch of steam and smoke came out and my radiator was dry. To keep it running i had to have the engine revved and at a stop sign hold the brake down. and slightly press. I'm assuming its the water pump however. It started yesterday as the colder weather started. What my question is what do you think it is and if you have experience with water pumps, how hard is it to replace i found one for $14
that don,t sound like the water pump. if it was the pump then it would overheat and leak out. check to see where it,s leaking at. if it,s leaking from the pump then it will have to be changed even though it still might not help it to idle. it,s not really that hard to change the pump on a 351W . the hardest part is getting into it. you might have to remover some stuff so you can work. the belt and water pump pulley will have to come off and the fan but that should let you into the bolts.
Q:I have two water well good water but not a lot of water .is it possible to hook two pumps up to one holding tank . if so how do I hook them up
it is very easy to do just email me. I'll send direction . I would say you have a small under ground stream of water . as you use the water from the well, it will take time to fill the well pipe again
Q:I want to build a portable, working steam room display for trade shows. I need to feed water from a storage tank to a steam generator when it's called for. How can I do this? Is there a type of water pump that would work for this?
Be careful what you buy. Most aquarium pumps are AIR pumps. Why not just use a siphon? As long as the storage tank is higher than the generator it will work. Get a hose or plastic tubing of the size you need, put one end in the tank. Suck on the tubing to start flow. To stop flow just pinch off the pipe or raise the spout above the water level. you might even install a valve if the tubing is large enough.
