Frequently Asked Questions - GL500-2-1 Global Water
How do I prime the GL500-2-1 pump?
This is a submersible pump, so it self-primes when placed underwater. Ensure the pump is fully submerged before turning it on. The inlet screen prevents debris from entering, keeping the impeller operational.
What is the maximum flow rate?
The GL500-2-1 delivers up to 5 gallons per minute (19 liters per minute) at no head. Flow decreases as discharge head increases.
Can the pump run dry?
No, running dry can damage the seal and impeller. The pump should always be submerged in water before activation.
What type of power supply is required?
The pump operates on 12 V DC power, drawing up to 4.5 amps. Use a suitable battery or power supply with the correct voltage and capacity.
How do I clean the pump after muddy water usage?
Rinse the pump with clean fresh water, paying special attention to the inlet strainer and impeller area. Allow it to dry thoroughly before storage.
Is the GL500-2-1 pump submersible?
Yes, it is fully submersible with an IP68 rating, meaning it can be operated underwater at depths up to 20 feet (6 meters).
What are the dimensions and weight?
The pump measures 10.5 x 4.2 x 4.2 inches and weighs about 4.5 pounds, making it compact and portable for field use.
Can I use the pump for saltwater?
The pump housing is made of reinforced polypropylene and the shaft from stainless steel, which offers good corrosion resistance. However, prolonged use in saltwater may degrade components. A freshwater rinse is highly recommended after saltwater use.
What is the included cable length?
The pump comes with a 6-foot (1.8-meter) power cable. Extension cables can be used with the appropriate gauge to prevent voltage drop.
What spare parts are available?
Spare parts such as impellers, seals, and strainers are available through Global Water's service center. The design allows for easy replacement of these wear-and-tear components.
