Self-Priming Chemical Centrifugal Pump – Model 80HZ50-30
A Real Request from Brazil
A Brazilian customer recently needed a self-priming chemical centrifugal pump. He was very clear about one thing:
Standard end-suction pumps would not work for his application.
After reviewing his requirements, we recommended the CIXIFM 80HZ50-30.
Here is why.
What the Customer Needed
The customer provided the following key parameters:
-
Flow: 50 m³/h
-
Head: 30 m
-
Speed: ~2900 rpm
-
Motor power: 7.5 – 11 kW
-
Pump type: Self-starting, horizontal end-suction, self-priming
-
Wetted parts: SS304 or SS316 stainless steel
-
Seal system: Double mechanical seal (tandem) with integrated cooling pot
-
Instrumentation: Temperature sensor and liquid level indicator
-
Motor: Explosion-proof Ex d IIB T4, 380V/50Hz
-
Application: Chemical liquids, continuous operation
These specifications point directly to a self-priming pump, not a standard centrifugal pump.
Our Recommended Model: 80HZ50-30

Why a Self-Priming Pump?
A standard end-suction pump cannot handle suction lift or air in the line without manual priming.
A self-priming chemical centrifugal pump offers:
-
Automatic air removal from the suction line
-
No foot valve or manual priming required
-
Reliable start-up even with intermittent operation
-
Better performance for chemical transfer applications
For continuous chemical liquid handling, this reliability is essential.
Sealing System for Continuous Operation
The customer required a double mechanical seal in tandem arrangement with a seal cooling pot.
Our 80HZ50-30 delivers:
-
Primary and backup mechanical seals
-
Circulating coolant to prevent overheating
-
Temperature sensor for monitoring
-
Liquid level indicator for quick visual check
This setup ensures long, trouble-free operation with chemical liquids.
Explosion-Proof Motor
The Ex d IIB T4 motor means:
-
Ex d – Flameproof enclosure
-
IIB – Suitable for typical industrial gases
-
T4 – Maximum surface temperature ≤135°C
This makes the pump safe for hazardous environments such as chemical plants and paint facilities.
Power supply is 380V/50Hz, matching the customer’s local standard.

Who Should Consider This Pump?
The CIXIFM 80HZ50-30 is suitable for:
-
Chemical liquid transfer
-
Paint, coating, and resin applications
-
Solvent and mild acid handling
-
Processes requiring suction lift
-
Hazardous areas with explosion-proof requirements
If your duty point is close to 50 m³/h at 30m head, this model is worth eva luating.
Final Thoughts
If you need a self-priming chemical centrifugal pump with:
-
50 m³/h at 30m head
-
Explosion-proof Ex d IIB T4 motor
-
SS304 or SS316 wetted parts
-
Tandem mechanical seal with cooling pot
-
Horizontal end-suction self-priming design
…then the CIXIFM 80HZ50-30 is a reliable, proven solution.
