3. Wide passage
4. ISO9001

Specifications:

1) General description:

Type G(or GH) gravel pumps are the series products introducted from Australia. Gravel pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in Mining. Explosive-sludge in metal melting, dredging in dredger and course of rivers, and other fields. Type GH pumps are of high-head ones.

Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage. The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys. The discharge direction of pump can be oriented in any direction of 360°. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance.

2) Features:

1,Horizontal, cantilevered, single-deck structure, centrifugal pump.

2, Large internal passages reduce internal velocities maximizing wear life resulting in lower operating costs

3, Easy installation,discharge outlet can be adjusted at any direction of 360.
4,Cylinder bearing assembly,grease lubrication ,adjusting the distance between impeller and pump.

5,Mechanical seal, expeller seal and packing seal for selection.

Q: what is NPSH for the water pump. Can you anyone explain in details? How can it calculate?: NPSH stands for Net Positive Suction Head. It usually refers to the amount of pressure needed at the inlet of the pump for the pump to work properly. If there is insufficient pressure pushing the fluid into the pump, and the pressure at the inlet is lower than the NPSH requirement, then the pressure will be so low in the sucking center of the pump that the fluid will boil (this is called cavitation). It usually makes a racket, reduces pump performance, and erodes away the pump. To make sure this doesn't happen you have to have enough head (as in some level in the tank feeding the pump) and low pressure drop on the way to the pump (meaning big enough lines, no obstructions, and not too many bends). Some pumps are designed for very low npsh requirements. These pumps can suck water from some depth without cavitating. No pump can suck room temperature water from fore than about 25 feet below the pump, because the vacuum needed to lift the water 25 feet or so is close to the vacuum needed to boil water at room temperature. You cannot easily calculate the npsh a pump needs. This is a function of the design and geometry of the pump. You can calculate the delivered npsh by figuring the pressure of the liquid in the feed tank (don't forget atmospheric pressure) and subtracting the pressure loss due to friction in the piping between feed tank and pump. This loss will be a function of flow rate. Faster flow, more frictional pressure loss.

Q: there is a knocking noise coming from the water pump pulley..i think, the pulley also wiggles when its running. If that's what is wrong, how long do i have to fix it and is it hard and expensive to fix?: No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!

Q: Looking for a pro's advice here. My Corolla has developed a strange noise over the past few cold weeks (Highs of 10 degrees max, well below zero at night). The sound would best be described as a cricket-type rythmic chirp noticable during acceleration. I don't believe it's a belt because it comes and goes though it has steadily gotten louder. I vaguely remember this sound being related to a bad water pump I had a few years ago. Do you think this could be the same thing? Three years for a water pump? And do water pumps tend to go out more frequently in the cold weather? Thanks!!!: First, you need to remove alternator belt and see if the noise disappear. then remove the AC (compressor belt) and notice if the noise disappear last , remove the power steering belt and see if the noise disappear IF NONE OF THESE STEPS HELP TO DETERMINE THE NOISE THEN YOU MAY HAVE TENSIONER TIMING BELT OR IDLER TIMING BELT OR WATER PUMP IS MAKING NOISE.

Q: Could someone tell me the procedure for removing & installing a water pump on 97 buick skylark 3.1L 3100 SFI?: Get the Chilton manual.

Q: When I buy submersible pump, the other party did not inform is the aluminum submersible pump, water pump factory production of aluminum submersible pump illegal? Is it against the law to sell the pump to the pump without informing me?: When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.

Q: need step by step on how to change water pump: steps okorder /

Q: Im replacing the water pump on my cougar but i ran into a snag. I got the pump unbolted but to take it off, i need to unbolt a bracket that goes behind the power steering pump pulley. I cant figure out how to get that pulley off to take off the bracket. Any help with this would be greatly appreciated. Thank you.: remove radiator,remove fan blade,you may have to move the a/c condenser and or compressor. and move the alternator out of the way. scrape gasket off engine block. glue new gasket to water pump and install in reverse. be sure not to over tighten the bolts.

Q: Level 200 meters distance, elevation 30 meters, how much lift water pump?: According to the horizontal distance of 10 meters is 1 meters lift, 200 meters is 20 meters and 5 meters height difference of 30 Mega elbow, pump head floating down 10%, should be about 60 meters.

Q: the water pump from the factory has an extra hole coming out the side its the smaller one on the end of this pic.: This is your recirculating pump. If it is a marine pump, it will have a brass backed seal and no heater hose outlet. (have seen them in the casting, but no hole there) The only difference is the casting, as long as it was ordered for the boat, you should be OK. For got to ask, do you have a cabin heater in the boat?

Q: I was wondering if the noise from a water pump can bother my crested gecko. I have a water pump that cycles the water that is in the leca balls, it does not make a load noise but the noise is there. Will this bother him?: It could potentially. Just see how he does-any decrease in activity or appetite-86 the pump
