Newa Maxi MJ 500 — Submersible 500 L/hr Pump

Newa Maxi MJ 500 — Submersible 500 L/hr Pump for Small-to-Medium Hydroponic Systems

Submersible water pump for small-to-medium hydroponic systems and components — Brain Buckets, water tanks, and NFT trays. Fully adjustable water flow, noiseless operation, built-in protection prevents overheating even if the impeller jams or the pump runs dry. Low power consumption suits continuous-running setups. The reliable workhorse pump for smaller hydroponic builds.

Why growers choose the Newa MJ 500:

• 500 L/hr flow rate — right-sized for small-to-medium reservoirs and recirculating systems
• Fully adjustable water flow — dial in exactly the rate your system needs
• Noiseless operation — suitable for quiet grow spaces
• Built-in overheat protection — prevents pump damage if jammed or running dry
• Low power consumption — cheap to run 24/7 in continuous-circulation setups
• Newa proven brand — reliable Italian aquarium pump manufacturer
• Submersible operation — sits in reservoir, no external mounting

Who it's not for:

For larger reservoirs (over 200L), step up to the Newa MJ 1000 (1000 L/hr) or larger pumps. For very large commercial systems, AquaKing Q50011 (10,000 L/hr) is appropriate. Must run submerged — never dry-run for extended periods. Match flow rate to your system's demand; oversized pumps in small systems waste energy and can over-circulate.
