ATACH DZA(S)50-32-160/ 2.2 stainless steel centrifugal pump offers better cost performance than the ZS50-32-200 /3.0 stainless steel pump

Similarities

1.Both use standard motors instead of extended-shaft motors, allowing customers to purchase replacement motors locally with ease.

2.The overall external dimensions and appearance of the two pumps are nearly identical.

3.Both pumps are fabricated from stamped stainless steel.

Differences

• ZS50-32-200/3.0: Flow rate 3~20 m³/h, Head 34.9~28.9 m

• DZA(S)50-32-160/2.2: Flow rate 0~20 m³/h, Head 37~27 m

  Judging from the flow and head range, the DZA(S) covers a wider operating window while only requiring a 2.2 kW motor. This is a key advantage: 3 kW motors carry higher procurement costs, and result in greater power consumption during operation.

  2.Pricing: With identical configurations, the ZS model is more expensive than the DZA(S).
  3.Motor pole options: The ZS can only be fitted with 2-pole motors, whereas the DZA(S) supports both 2-pole and 4-pole motors.
  4.Motor type options: The ZS is only available in the standard motor version. The DZA(S) can be supplied with either standard motors or extended-shaft motors, delivering better cost performance. The extended-shaft variant is designated as the GZAS series. Customers may contact ATACH Pump sales department for further information.
  5.Market maturity: The DZA(S) series has been in production and field service for a longer period. The ZS is a relatively new product. Its design flaws and corresponding troubleshooting solutions are less mature, which introduces potential risks in long-term operation.
