 Products: 
 I. Product Overview: 
 DL Vertical multistage centrifugal pump is efficient use of national energy-saving products recommended IS pump hydraulic model for the vertical multi-level multi-segment 

 Structure. Screw the inlet, middle, clamped into one section of the water. Install a water pump impeller every level, a guide water Leaf. 

 Axial force using water balance method to solve the residual axial force by the ball bearings under shaft with grease. Seal or soft packing machine 

 Mechanical seal. Product implementation JB/T2727-93 "vertical multistage centrifugal pump types and basic parameters" standard, primarily for smoke delivery diluted 

 , Clean, non-corrosive, non-explosion of water and physical and chemical properties similar to water without solid particles or fibers of the liquid. 
 All of our products designed and optimized using computer processing, the company has strong technical force, rich production experience and perfect 

 Detection means, to ensure stable and reliable product quality. 

 Second, the scope of application: 
 Widely used in high-rise building fire and life cycle of water supply and air conditioning units, cooling water transport. 

 The product features: 
 1, advanced hydraulic model: high efficiency, wide range of performance. 
 2, novel structure, reliable operation: the abolition of the balance drum, the axial force the use of water balance, easy to solve the balance of corroded drums 

 , Easy to bite, easy to wear, to ensure reliable operation. 
 3, less operating and maintenance costs: the use of high-quality mechanical seal, wear-resistant, leak-free, long life, low failure rate, 

 Run with less maintenance costs.
