Peripheral Pump

The pump is with peripheral impellercontaining numerous radial blades in its edge. Water is threw outwards bycentrifugal motion caused by the impeller. Then the water rotates with theimpeller, generate high pressure. These pumps have a compact size and are veryeconomical.They have various appearances and motor shells to the differentoperating requirements

Pump body:Cast Iron

Impeller:brasss

Motor:Closed, Externally ventilated

Insulation class:B(Class F if required)

Protection class: IP44/IP55

Mechanical seal:Φ12 ceramicsteatite/graphite

Shaft:Carbon steel AISI 1045(Stainlesssteel AISI 420 if requied)

The normal power standard is220v,50HZ,single phase

Three phase 220v/380v, 50HZ, 220V/460V,60HZ

Single phase 230V, 240V, 127V,110V,115V/60HZ

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: I have a 1969 Chrysler with a new 3 core radiator. It still has the stock water pump and I am wondering if a high volume pump would make it run cooler at higher speeds. It runs hotter when you get off the freeway. I have flushed the system and installed a new thermostat. I also replaced the fan clutch. I am at a loss of why it still runs warmer than the 180* thermostat.: maybe the fan is too far away from the radiator to efficiency pull the air at slow speed. They sell spacers.

Q: model # gg9002b serial # 65x626092 what year is it and what is the water pump number: www.okorder /

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 have a water leak, and not from the radiator. It is on the side of the motor where the timing belt is. Could it be the water pump? or possibly freeze plugs? If so where are these?: Its located under the timing belt cover. Time to replace both the belt and water pump while you or your technician are in there. $500 at dealers typically.

Q: How can I test to be sure my water pump is working before I go to the lake and burn up my motor. `72 65hp johnson. thank you.: You can also go to a marina and buy earmuffs that hook to a garden hose and fit over your water intake. As stated above just look for a stream of water coming out the back of the engine.

Q: What is a 1 inch water pump?: The caliber of the water inlet and outlet pipe is 1 inches of water pump,

Q: I have a pump connected to a lake, that I use to water garden. I changed the line into the lake as it had a air leak and lost it.'s prime.I have filled water back into the tank and lines .several times. And it hasn't caught it's prime. It is a year old pump that came with it's own tank.When I am doing all this I leave the tap end closed.I'm pretty sure that all is tight and not leaking.The line into the water is only about 5ft deep: The hose that connects to the lake should be filled with water to prime it.

Q: Why should the pump fill the air before running? What's the reason why the water doesn't go up?: By rotating the water pump is thrown from the impeller center, resulting in pressure, the back of the water sucking over, this is the pump working principle, if air, air will not be left out without impeller, the flow rule, no pressure, so we can not draw water!

Q: I want to run 1 HP, 220 v, single phase water pump on solar panels without using any batteries. what do I need to do so amp; how do I wire it?: Several huge panels, into an inverter than can provide the required amperage. You realize the pump will only run when the panels are receiving light, don't you? While you may not wish to use batteries, without the batteries the system will only work when and if it gets enough sun to actually provide the required power. It may actually burn out the system or even the motor trying to run on less power than it needs.
