Applications of the Crocodile water pump below 50m3/h
Domestic and small business wastewater pumping: Used to transport wastewater from households, small restaurants, or medium-scale business facilities, even when the water contains mild sediment.
Pond, lake, and irrigation canal pumping: Draws water from small ponds, lakes, or canals containing mud and small debris to serve crop irrigation and medium-area agricultural activities.
Local stormwater drainage: Applied in stormwater drainage systems in low-lying areas, yards, or small construction sites, helping to mitigate localized flooding.
Light industrial applications: Used in several small production processes to pump low-viscosity liquids containing mild sediment, meeting basic water treatment needs.

Advantages of the Crocodile water pump below 50m3/h
The crocodile water pump below 50m3/h not only stands out for its compact design but also possesses many practical advantages, suitable for residential and light industrial needs. Below are the notable strengths of this product line:
Easy installation, stable operation: Compact design, plug-and-run, suitable for various spaces and placement positions. The pump operates stably even in wastewater environments containing impurities.
Puts up with mud and small debris: With a wide suction port and anti-clogging design, the pump can draw water mixed with dilute mud and small organic debris, helping to clean effectively without worrying about impeller jams.
Effective flood prevention: The pump is commonly used in sumps, basements, and workshops to handle flooding quickly and promptly.
Automatic operation with float switch: Integrated with an automatic shut-off float, helping the pump automatically turn on/off according to the water level, saving electricity and protecting the motor from dry burning.
Durable, low maintenance: Using corrosion-resistant materials and a well-protected motor, giving the pump a long lifespan with minimal repairs required.

Why does a cast-iron crocodile pump head often develop yellow rust and cause the impeller to jam tightly when left unused for a long time?
Due to the characteristic of the pump chamber being made of cast iron, it will generate a layer of rust when exposed to water and oxygen. If stopped for a few weeks, this rust layer thickens and tightly binds to the very small clearance between the impeller and the chamber flange. To handle this, customers must absolutely not try to turn on the power (causing motor burnout), but instead use a screwdriver to gently pry the cooling fan propeller at the rear until the shaft turns smoothly before turning on the machine.
Why do crocodile centrifugal pumps used for digging wells or underground tanks very often lose their priming water?
Unlike vacuum pumps that can automatically suction air, crocodile centrifugal disc pumps require the pump chamber and suction pipe to be 100% full of water so that the impeller can create centrifugal force to pull the water up. The loss of priming water is largely due to the foot valve (check valve) at the bottom of the well being loose, debris stuck in the rubber gasket, or cracked suction pipe joints allowing air leakage. Customers need to check the tightness of the foot valve and the suction piping system.
Can the flow rate of this small crocodile pump be increased by changing the size of the suction/discharge pipe?
It can be optimized but cannot exceed the rated level. To achieve the best flow rate for the machine, customers should keep or expand the suction pipe up to 1 size to reduce flow resistance. However, if customers squeeze the discharge pipe too small to push water far away, the outgoing water flow rate will experience pressure drops and fall far below the manufacturer’s specifications.
