Q: A direct type pump model with the coupling type, what is the difference?: The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.

Q: I just posted another question a few minutes ago, but not really much help with the one answer I got. I'm now sure that what part I'm feeling on the back of the engine block is the water pump on my 97 Grand Am 2.4L twin cam POS car. I somehow got my hand back there enough to take pictures to see what I'm feeling. Noticed in one of them that there is a bolt missing! This area was very wet with coolant. Would this bolt missing cause the pump/cover to leak? Makes sense to me. If all the bolts aren't there, then there wouldn't be proper seal, right? Had this engine put in a few months ago. The guy who did it seemed to miss a lot of things.: /i thini it might... I would just get a bolt from a local carquest, autozone, aidauto where ever cant be anymore than 5 bucks... best best better than overheating your engine and getting stuck for a couple of bucks

Q: A guy i know changed the Water pump on my 02 Chrysler Sebring with a 2.7 in it because it was leaking coolant, when i got it back the leak was fixed but now there is a ticking noise. He thinks that the Timing Chain Tensioner needs to be replaced... can i get some opinions here? does he sound correct?: It is possible. The water pump is driven off the timing chain on that engine. Why didn't he replace the tensioner when it was apart is a good question. The fact that it is now ticking isn't a good sign. I hope it was lined up properly.. get it looked at soon before there is the potential for damage.

Q: I was wondering if water pumps make any noise when they are submersed? Also, my pond is quite small and I don't want to scare my fish with a noisy pump. Thank you!: i've got efficiently used that pump for ten years, recirculating water interior a fountain. it quite is not submerged and is thoroughly silent as long as you do no longer permit debris accrue on the impeller section. I double filter out the water earlier it is going into the pump. that's wiped sparkling via unscrewing the bleed-valve on the top and letting the debris be cleared. you could take it aside there, too, yet take care re-assembling because of the fact the o-ring is comfortable.

Q: Two sewage pumps switch from each other, start with float switch control, the first sump, when the water is full, the first start, the second rotation to second units start, so the cycle of alternating: Can add time delay relay, the key depends on how much time the water is full, if you design is automatic, it is better to use the triode reliable,

Q: Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?: The condensed water is also used to air pumping device, steam seal cooler as cooling water, according to rules of turn.The circulating water is also used to supply cooling water to the oil cooler, and the oil temperature will rise.Hazard: exhaust pipe, condensate pipe will burst tube, low pressure cylinder rising temperature for deformation, rotor (shaft seal) may be deformed.

Q: I just got a new boat with a diesel engine and I don't understand why there is a coolant tank as well as a water pump? I think the water pump goes to the heat exchanger but what actually cools the motor - how does this stuff work?: this is refered to as a fresh water cooling system. the engine has a coolant tank and a recirc pump that pumps the coolant through a tube and shell heat exchanger,just as a car does through a radiator. instead of air around the radiator, the exchanger has sea(lake)water pumped through it by a engine mounted pump or a pump on a outdrive if so equiped. the engine heat is transmitted from the engine coolant to the exchanger, and out to the sea(lake). this system has many advantages. one of the most important is the fact that salt or brackish water never touches the engine block or components, preventing costly corrosion. secondly it keeps the engine running at a more even or constant temp. this is very important to a diesel as the engine puts out its hp and performance at a set temp. the heat exchanger can have an automatic drain system, draining water out of it and with coolant (antifreeze) in the engine, the boat can be operated in freezing weather without freezing, or draining the block every night. Heat exchangers can be backflushed easier than an engine, and allow the boat to be operated in muddy or contaminated water. (I have seen boats with tandem exchngers in case one plugs up or needs cleaning). gasoline and diesel engines can have exchanger systems, but since diesels inherantly are more expensive and live longer, a heat exhanger system is worth while.

Q: Im half way through replacing my water pump and im stuck...the power steering pump pully blocks access to the final bolt that needs to be removed so the water pump can be removed so i can replace the water pump... any hints on how to get to the bolt so i dont disassemble something i dont need to?: 2003 Impala Water Pump

Q: The pond is 10' long x 2' wide x 1' deep. The pump is at one end and water is raised 1' to a buried garden hose that is maybe 12' long and then at the end it goes up 2' to release the water over some rocks. I had a 330 gph pump that worked well but died. That size has been discontinued. Go smaller or bigger? DON: Hi Don, In my point of view it depend on the final effect that you want to create. If you are in the mood of water theraphy, mean that you like to the sound of the water fall, you may want to consider a pump size that a bit higher than your previous ones, and vice versa. In a nutshell you should be able to determine the effect of the waterfall you need since you already have your previous old pump running before.This should be your best guideline to check the size of your new pump needs. There is a bit of extra caution needed if you are thinking of using a bigger size of pump, you should ensure that the pump are not sucking to fast of the water. If this is the case you might be end up having your pond drain half tank. You can get the circle time for the water flow base on the pump size from the catalog.I'm sure your hardware guy are gladly assist you in understanding the matrix conversion Pond size over the pump size,since I can't explain in detail here about the graph reading. But in most cases I just relatively using the first option of comparing the old pump size with the new one. Hope that help. Fazla

Q: hooking up a water pump to my tank and need a power supply: can you be a bit more descriptive have you a pump but no way of powering it if so what type of pump what voltage where is pump
