Growonix Delivery Pump - 4 GPM - 55 PSI - 1/2-in O.D. Tube Port - Variable Speed

Adjustable Water Delivery for Compact Irrigation Lines - 4 GPM

Water systems rarely need the same output all day, and a fixed-speed pump forces you to throttle flow with valves. This pump has variable speed, so you tune delivery to the system in front of it. A high pressure cutoff and thermal shutdown protect the pump and your plumbing.

At 4 GPM maximum flow and 55 PSI maximum output, this single unit suits small to mid-sized hydroponic setups, nutrient delivery lines and irrigation runs where quiet, compact operation matters more than bulk volume.

Key Features & Benefits

• Variable speed — match output to the needs of your water system.
• High pressure cutoff — shuts the pump down under excess pressure to protect lines and fittings.
• Thermal shutdown — guards against overheating.
• Can siphon — handles setups where the water source sits below the pump.
• Optional heat sink — cools the pump and extends its duty cycle.

Who Should Use Growonix Delivery Pump

Growers running hydroponic systems, nutrient feed lines or small irrigation circuits who want adjustable flow in a compact, quiet pump. It suits intermittent duty rather than continuous running.

Frequently Asked Questions

Q: How much water can this pump move?
A: Its maximum flow rate is 4 GPM at 55 PSI. Because it is variable speed, you can run it below that to suit your system.

Q: Can it run continuously?
A: It is rated for intermittent duty. An optional heat sink cools the pump and extends its duty cycle.

Q: What happens if it overheats?
A: Thermal shutdown stops the pump to protect it from overheating. It also has a high pressure cutoff for excess pressure.

Q: What does variable speed mean?
A: You can change how fast the pump runs and so how much water it delivers. This lets you match output to your system without relying only on valves.

Q: Can it siphon?
A: Yes, this pump can siphon, which helps when the water source is positioned below it.
