A: First of all, confirm leakage part is in the sealing ring or in the sealing ring for corrosion, or in the surface of the friction pair for damage. It is necessary to decide the medium condition of the pump, like whether there are impurities in the medium. Different medium needs corresponding material of corrosion-resisting sealing roller, the medium within impurities grain needs configurating special anti-friction sealing cover.
A: you can find it in the the packing box.
A: CDL (F) series ordinary type and stainless steel type are exactly the same in performance curve.
A: All CDL(F) series in our company are connected with couplings.
A: The water pump produced by our company can be judged from three points, 1. Pump invoice number, Q beginning 2. Factory number, a total of 10 digits 3. Bar code
A: Is the machine seal burnt out? If so, it may be caused by the friction burn out due to solidified grease adhering on the gap between the friction pair and preventing circulating water from entering. You can order our special type of knife edge machine seal to solve the problem, thank you.
