Warman pump curve information you should know
Warman slurry pump is the world most famous slurry pump.
And when you need to check the pump information, there is very important data you show know: curve.
The pump curve is tested drawing to show the pump information. Such as material, shaft seal, speed, capacity, head.
Bellow is one common warman pump curve
As you can see, the Curve chart head show the information of the company and some pump information as, impeller, shaft seal, material
1 Pump head
On the picture, NO. 1 show the pump head information, such as 10, 20, 30 all in meters. Head is the height at which a pump can raise water up. This decide the pump transport performance.
2 Pump speed
The data on the picture shows 1000, 1200, 1400r/min
3 Pump efficiency
This data is the pump efficiency on picture No. 3. Pump efficiency is defined as the ratio of water horsepower output from the pump to the shaft horsepower input for the pump.
4 Pump Capacity
No. 3 on the picture is another important information for warman pump. This data shows the pump capacity.
