Q1: When the middle-opened pump equipped with machine seal needs changing the packing, is the shaft in this pump universal?
A: A: Yes, it is universal, but the sealing body, shaft bushing, gland, bolts, fittings and joints must be replaced 

Q2: Pipe pump is used in the degreasing process before painted, and the shaft seal is often leaking even be replaced for several times. How to solve this problem?
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.

Q3: Where can I see the installation instructions of CDL pump?
A: you can find it in the the packing box.

Q4: whether the CDL15-10 and CDLF15-10 pump are only different in the base stainless steel, is there any differences in their performance curve?
A: CDL (F) series ordinary type and stainless steel type are exactly the same in performance curve.

Q5: Is there coupling in CDL15-4 ?
A: All CDL(F) series in our company are connected with couplings.

Q6: A circulating pump used in our company are seriously leaking. It is unknown whether the pump is come from your company?
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

Q7: Nowadays, a mechanical seal centrifugal pump is used in playing wastewater use, wastewater containing small molecules of resin, which solidified upon the temperature coming down, which resultedmechanical seal broken down in two days. I would like to ask whether there is a good way to solve this problem.
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.
