Product Description:


TPWA Horizontal Multistage Centrifugal Pump

Product Introduction:
  TPWA series multi-stage centrifugal pump is horizontal, single-suction multi-stage and segmental, which is an energy-saving series of product developed and produced lately, a new product based on the major technical improvement for TPWA mutli-stage centrifugal pump. Its performance parameters and technical indexes have all been improved significantly, so it has much noticeable advantages as high efficiency, low running noise, strong cavitation resistance, reasonable structure and long service life.
   The full line of TPWA multi-stage centrifugal pump includes 5 type and 40 specifications, whose performance range is:flowQ=1.5~191m3/h, lift head H=17~247m and rotation speed n=1450r/min.    TPWA multi-stage centrifugal pump is used to transport the clear water or other liquids with similar physical and chemical propertiea as clear water with temperature less than 80℃. It is widely applicable for water supply and drainage of city buildings, factories and mines, especially for refrigeration and air-conditing water supply in guesthouse, hotels and recreation areas.

Q:Suppose the liquid temperature range for the water pump is -20 .. 90 °C.?
(edited) The physical size of the pumping arrangement was not described. I assume that the pump has all metallic components because of the high (194 F) 90degC design operating temperature. There may be some problem with an elastomeric bellows in a mechanical seal at the 180degC (356F) temperature. Other than that, there should be no problem with the temperatures as far as the pump is concerned. There may be a need for shaft cooling to protect the standard electric motor and possibly the flexible drive coupling arrangement. (edit) Depending on the physical size, rotating speed and drive arrangement, a special coupling set-up may be needed to accommodate any potentially wide swing in operating temperatures. From ambient to 180degC there will be about a 160C (288F) variation. The liquid will be either a salt or a glycol brine solution for freeze protection at the lower temperatures. (edit) That same concentration will provide some elevation of the boiling temperature and therefore a reduction of the pressure of the water solution needed to prevent boiling. ( 130 psig is the saturation pressure of plain water at that elevated temperature.) This can be found on the charts provided by the glycol suppliers for the various glycol and salt solution characteristics. To prevent cavitation you may need to pressurize the suction. If the proposed pressure of the system is already above the vapor pressure of the solution at that maximum temperature, you may already be OK. A motor with high temperature windings may be considered.
Q:Can a leaking water pump ruin brake lines?
Ray hit it on the head so just wanted to add that rubber brake lines are made of a material that will not dissolve or decay with brake fluid, oil water gas and any other road contaminate you will encounter. The water or antifreeze on the timing belt or any belt for that matter will ruin the belt because it acts like a lubricant and cause's the belt to slip and eventually fail. I wanted to add that the lines on the front wheels have rubber hoses on them only the rear normally have steel lines.
Q:2002 Mitsubishi eclipse water pump?
i would get out of that thing they are nothing but trouble always! a have a freind got a nice chevy ,never been happier?
Q:Adjust belts and change water pump on 02 Accord?
The water pump is driven by the timing belt. I do the water pump and timing belt with the pulleys and tensioner for around $600. If the drive belts are making noise try dusting some talcum or body powder on them. Don't use belt dressings, they never work.The timing belt should be replace around 90,000 miles so if that hasn't been done you should have it replaced or you will bend all the valves when the timing belt jumps or breaks. That's a 14 year old vehicle and the timing belt needs attention.

Q:Why can't vertical water pump use spring shock absorber?
Vertical pump can use spring shock absorber, because the bottom of the vertical pump installation area is small, so many people feel that it can not install spring shock absorber, actually not, and now there is a vertical pump can use the shock absorber;Introduction of spring shock absorber for vertical pump;1 、 spring cover and spring seat for the combination of butyl glue and cast iron, and after baking treatment, good weather resistance.2, according to simple installation, bolts can be used to adjust the height and level.3, can be matched with the pedestal design, can be used in various types of machinery and equipment.4, applicable to all types of pumps, fans, air conditioning boxes, pipes and so on.
Q:how much does it cost for a water pump for a 97 Chevy lumna? I am breaking up with my boyfriend and he paid
I don't know so much about legal issues, but 4-500 dollars for a water pump sounds about right. The pump costs about 80 but you have to take out the engine to get it. Usually when they replace the water pump they'll replace the timing belt, too, which again adds to the cost. If he takes the pump out, it means the engine will be out, too. Engines are really heavy, so I doubt that he could do it on his own. If he has a mechanic do it, the car will be stuck at the mechanic's until you get a replacement part, and he still has to pay $300 in labor just to get the thing out of there. It is pretty much, then, an idle threat. He could however, do quite a lot of damage to your car with a hammer. However, that would be vandalism and he would go to jail for it. If he has already paid for the repair, he can't really sue you. He can, but the judge should look at it as a gift, which he can't get back.
Q:are duralast water pumps any good?
Point blank, ask the folks at Auto Zone where this water-pump was produced. If it was re-manufactured off-shore leave it on their shelves. I trust you knew these Duralast water-pumps are re-manufactured. All AC-Delco starters, alternators and water-pumps are re-manufactured in the USA. Every part inside the reused housings are factory brand new with parts made here in the US.
Q:Do you need a stop valve for the pump at home?
It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
Q:How hard is it to replace a water pump?
The first answer gave good advice. On older cars replacing a water pump was easy. You loosened the fan belt, removed it and removed the pump with the fan blades. Now nearly all autos have air conditioning and there is not enough room without removing some of the items associated with it. I have on occasion even had to remove the radiator before air became popular. Shop around for an independent mechanic or a small shop. The job will be more than you want to try probably. Good luck.
