Product Description:

ADVANTAGE:
<1>Electrical motor:

High-performance water-resisting squirrel-cage-type motor, Class H stator winding (≤180°C) and longer service life. IP68 protecting class, inserting heat sensor for each phase of stator winding. Direct starting for 3 kW or 3 kW below, ?starting, reduced voltage starting or soft starting for 4kW or 4 kW above.      
Electrical motor also applies to other voltage and frequency.
Fire proof motor conforming to international standard and applying to dangerous occasion is optional, for example dIIBT4etc.

<2>Shaft bearing :
Service free upper/lower shaft bearing is designed as 50000 hours service life, and assembly of temperature probe according to requirement is allowable.

<3>Cooling system:
Cooling system is divided into open-type circulation and cooling system and close-type circulation and cooling system, which ensures normal operation of motor below/above level surface.
Open-type circulation and cooling system: Pumps parts of liquid and circulates it from back side of impeller to clearance between tube cooler and casing to remove heat generated by motor, provided with excellent flow property and performance avoiding blockage  Close-type circulation and cooling system: Eliminate heat with build-in rotating wheel, which is provided with performance of blockage-less and service-less.

<4>Sealing:
Separate motor and pump with two layers of mechanical seal, which provides motor with diplex protection.Mechanical seal material at side of pump adopts tungsten carbide/tungsten carbide and it at side of motor adopts graphitetungsten carbide. Special device and spiral seal groove at backside of impeller provide the unit with long-period and Effective protection without enwinding.

<5>Shaft :
The unit adopts coaxial and shorter-overhang design, which depresses interference of shaft, reduces vibration, depresses noise and prolongs service life of mechanical seal and shaft bearing.

<6>Impeller:
Adopts CFD optimizing design, which transports liquid in perfect flow, speed and maximal efficiency without blockage. User could select impeller model as eddy flow, single channel, duel channel, or multi-impeller according to difference of
pumped medium.

<7>Cable seal:
Separated sealing connection box. Adopt waterproofing and sealing cable,  and  provide  inlet wire with  anti-tension  and anti-wind protection.

<8>Monitoring system:
Equip each phase of motor with temperature sensor that sends out alarm signal ands shut down power supply automatically if motor suffers from overheat.
Optionally equip upper/lower shaft bearing (s) with temperature sensor that sends out alarm signal ands shut down power supply automatically if motor suffers from overheat.Sealing monitoring device is used for monitoring if water immerges into oil chamber from shaft seal. In addition, there is set with individual sensor in motor chamber and connection chamber of motor of 30kW above, which should perform early warning if leakage occurred.

Q:how do i know if i need to replace the water pump on a 2000 kia sephia?
Your water pump should definately be able to be spun by hand. Generally when a water pump goes, or starts to go, it will leak antifreeze and or you will be able to shake the pulley slightly. Double check and try to spin the water pump again without any belt tension on it. A water pump can go at any time however, if your car has less than like 80,000 miles on it, it's probably fine.
Q:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
Imports, such as Schneider, press: plastic case press 250A, contactor select 115 of 2, 95 of 1 can.Domestic recommendations: Press: plastic case press 250A, contactor 160, 2, 115 of the 1 can.
Q:What if you don't know the cut-in pressure of your water pump?
Q:Volkswagen...Leak from the water pump housing... or something else?
Water pumps have a seal to hold the water from leaking out the spinning shaft, and the seal always wears out about every 100,000 miles. It is probably this seal that is bad, because it is probably the original pump, and you replace the whole pump. You have to take the front belt cover off and remove the timing belt, so it is not a trivial job. Cost about $300, and takes about 2 hours. But any friend who understands timing belts can do it easily. No special tools or tricks involved, other than making sure the cam timing is correct. Once you take the 3 bolts holding the water pump housing off, you can easily tell if any hoses or clamps should also be replaced. Do the thermostat while you have it off anyway. It is only $5.

Q:what kind of water pump will I need?
What you want is called a sump pump. Most have a system built into them that is triggered by rising water. The idea is to have a hole beneath that allows the inevitable water that will collect a place to go, then when a certain amount gets in the hole, the sump pump comes on and pumps it out to wherever you have the hose or pipes ran to. Being underground, good luck keeping the humidity level down. It won't be easy, and much depends on where your natural water table is, and what it is during rains. Someone in your area might know all that, I don't.
Q:water pump replacement mercury topaz?
contents no, replace component.
Q:Is the motor with a pump a squirrel cage induction motor?
Should be a squirrel cage motor for winding asynchronous motor for high torque applications. For example, its structure and the hoist crane cage motor with different rotor loop it can slip ring external resistor. The motor rotor circuit principle know that certain external resistance can reduce the starting current, but also can improve the rotor circuit power factor and torque. The pump load does not need large torque. So it should be the squirrel cage induction motor.
Q:Does a Water pump have to stay running?
No this is normal when you flush it should come on
Q:Electrical design into!!! Is the water pump lamp waterproof?
The ordinary pump houses are ordinary energy-saving lamps, but there is a glass shield outside of it which is waterproof...And they're all emergency lights!Like some large pump houses, they have riot lights...
