Product Description:

Application: The submersible reflux pump of Model SRP series is a product developed on the basis of the production technique of submersible mixers, it is a special equipment used for the reclamation of the mixed liquids, denitrification, denitridation and nitrogen removal in Class ll sewage treatment plant and also used in the locations which require low lift and large discharge in the ground surface water supply or drainage projects.

--------------------------------------------------------------------------------

Feature: 1. Special design is made to the operating mode of short lift and large discharge.
2. The main equipment employs the stainless structure of the punched components, resulting in very good hydraulic performance and high efficiency.
3. The integrated installation design can realize the quick underwater installation.
4. The dual mechanical sealing arrangement and a multiple of electro-mechanical protective function will improve operating reliability.

--------------------------------------------------------------------------------

USAGE CONDITIONS
1. The temperature of the media shall not be higher than 40oC during the continuous operation.
2. The pH value of the media shall be 5-9.
3. The maximum depth of submersion shall be 10m.

Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。1, the system is designed according to 2+1, 1 standby, only redundant backup of important equipment, not included in the running load.2, higher power distribution only provides 2 (maximum operating conditions) equipment rated operating power capacity (slightly margin, but limited).3, a single 160KW motor rated current is about 300A, 185 cable can only be used for the 1 pumps (with 2 units, and has overload) 630A circuit breaker is the frame level, if the current setting value is 630, it should be the main power switch (single pump with 400A circuit breaker, setting a value of 315 or 350A).4, if the 630A as the main switch to provide 2 pump power, has been close to full load (third pumps can not be added).5, water pipeline system, although not what caused the problem, but the water flow rate, flow rate of 2 pump operation should be in the ideal range, adding third pumps (the premise is to ensure the power supply) will make the water flow velocity is too large, in non ideal conditions.Conclusion: this method is inadvisable. If necessary, modify the original system, change to 3+1 mode, and change the line and circuit.
Q:can a failing water pump sound like rattling or popcorn until the motor begins to over heat?
Yes it can! I am curious though if what you are hearing is a really bad water pump or spark knock due to excessive heat or possibly a blown head gasket. Remove the belt and shake the pulley on the water pump. If it moves or rattles at all, then it is probably bad. Seems strange that it hasn't tossed the belt off though if it were that bad. Worth looking though, testing is free, parts are not....
Q:What is optimal on/off cycle for well water pump?
There is no optimum time. This is dependent on several factors. Assuming you are pumping into a small tank which is pressurized by the inflow of water from the pump (and the pressure also controls the pump) these reasons can be excessive use of water, the air space at the top of your tank has been absorbed into the water over a period of time and the volume of compressed air too small causing the pressure to drop too fast, or you could have leak in your water piping. If there is not enough air space in your tank, the pump will cycle extremely fast. If you don't have a tank, then the above information is incorrect. Good luck.
Q:2001 yamaha banshee, How should the water pump sit in the case?
Perhaps one of the shaft's retainers, the bearing, or gear is worn, allowing the water pump shaft to move in and out of the case - causing the impeller to rub on the outer cover. Try to pull the water pump out and push it in - there shouldn't be any play. If there is, figure out why. If the impeller can move in and out, that would cause it to knock. If there were any metal shavings in the coolant, they would scrape the outer cover. The water pump cover isn't an even shape, so I don't know what you mean by should it be in the center The bottom end and the cooling system are 2 separate entities. A problem with one will not affect the other.
Q:Will an F150 water pump work on an F100?
water pumps are related to engine families. not a weight class. in this era, w/o getting into what family engines share a given pump, i can tell ya, if it physically fit, in all respects, you're good. it wouldn't mount if it wasn't correct. ----------- there is some incorrect info here. like all manufacturers, there are a few different ford blocks of different cubic inch displacements that *do* share the same pump. 289/302 for only one example. that may or may not include a 351. there are 351 Cleavland's, M's, and Windsors.
Q:What is the difference between self-priming and non self suction?
Non self suction is the ordinary water pump for the water inlet pipe, but the flow of water is small,Self suction for the water inlet no water (that is, 4, 5 floor water, no water on the 6 floor), it uses the principle of negative pressure to suck up the water
Q:1990 gti water pump replacement?
Buy a repair manual. Or better yet buy a lifetime replacment one at Autozone and they will print out a step by step (with pictures torque specs) instructions for you. :)
Q:Will installing an upgraded water pump void warranty?
put it on...what if the stock pump wore out...you and most others will not put a gen u ine mazda pump on it...in reality its replaced with a aftermarket pump
Q:Bad water pump?
What ever it was it has the engine knocking. Its a little too late to wonder now. Sounds like it lost water and then kept running until she ruined the engine.
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
