It is NEW TWO-stage Cascade Pump Product of our series, with high lift value.       

Pump is equiped with DRY-RUN Protection mechanism in default.          

Inlet: 1/2” thread(M20) with external diameter of appr. 20 mm, outlet: 1/2” thread(M20) with external diameter of appr. 20 mm;

Max static lift: 32 meters;

This is a NEW series initiated by our company: 

If it is old users, you will know that our older single-stage pump DC50E-24150S model or DC55E-24160S model (with power consumption of appr. 80W and lift value of appr. 15-16m at 24VDC).

As a comparison, this current Two-stage cascade pump DC55JE-24320S model is obviously more powerful.

Specifications

Package includes:

1 x All-new Original DC55JE-24320S Micro Brushless DC Water Pump (Two-stage Cascade design) 

(No power supply is included:

       If power supply is AC/DC power adapter, output capacity of adapter should be 24VDC, 8A ~ 10A.)

P.S.: As we see on pictures, the connector of pump is with 4-PIN connector type, which is a bit special.

If it happens that our users find that we cannot conveniently find the matching connector for power connection, then there exists a simple while violent way.

In Brief, let's directly cut off the cable's connector and we will find that there are two sub-cables inside.

As to polarity, it will be typically RED +, BLACK -, connecting with matching 24V DC power supply.

Regarding corresponding pumps, there are some notes (Not only refering to current pump model listed on this page), As follows.

As micro brushless dc pump, it works via electronic commutation while not brush friction, so there exists no loss caused by brush friction. Pump works with relatively high efficiency.

Pump supports continuous long time work with relatively low noise at normal working environment.land use or submersible installation (Some extra attention needs to be paid to, as mentioned in the final clause) can be both OK, but it cannot be self-priming, just make sure that fluid can actively flow passing through inlet/outlet because pump works via centrifugal force of high-speed rotation of impeller inside (push/throw fluid out). No long-time dry work without fluid, or it may damage the pump.

DC 12V or DC 24V power supply (Depending on rated voltage of pump). No direct AC power powering or over-voltage powering.

Do NOT throw the pump or install it violently, as it could damage the pump body. Do NOT throw the pump directly through the cable, to avoid damage of cable. FIX the pump somewhere at work, to avoid its moving at run, causing little in-flow and dry run, though pump has dry-run protection mechanism designed inside.

If it is AC/DC Power adapter, make sure that it can offer sufficient power to pump. (For example, if it is 24VDC 100W pump, then AC/DC power adapter must have output capacity of 24VDC, >=6A; if it is 12VDC 80W pump, then AC/DC power adapter must have output capacity of 12VDC, 7A or more.  Otherwise, it is less powerful to run the pump. Other pumps will be applied with similar mechanism.)

Do not directly throw or pick the pump through its cable, since it could damage the cable, especially at connection point between cable and pump body.

IMPORTANT NOTE: Control box part (rectangle shape) is NOT recommended to be under water. It’s recommended to be placed off water, especially at long term work. If really have to, it is recommended that some firm waterproof tapes can be closely wrapped on the controlbox part before it is placed under water, to streghten its waterproof class. Just for in case. Sure, it is without issue if control box is just placed under water for short time.  

DRY-RUN PROTECTION feature is now equiped in the pump’s design. Pump works at rated voltage: when water flow is gone or in-sufficient, pump will auto access protection mode: run & stop, run & stop, ..., to protect pump’s motor part from being physically damaged from long time extensive friction and heat at continuous dry run; when water flow is back to sufficient status, pump will immediately normally run. This can help avoid that pump can be easily dead when it dry runs for long time. -- It is the NEW feature! (P.S.: Of course, very long time dry run will still need to be avoided by us as users, since pump won't stop but its running sharply slows in this context. )
