BioPro Hopar DC-18000 Controllable Water Pump – 16,800L/H

The BioPro Hopar DC-18000 is a powerful controllable water pump designed for large aquariums, sumps, ponds and water circulation systems.

With a maximum flow rate of 16,800 litres per hour, it provides strong water movement while giving you control over the output through the included controller.

Its compact design, adjustable flow and quiet DC motor make it a practical choice for high-flow aquarium and pond setups.

Key Features & Benefits

• Maximum flow: 16,800L/H
• Adjustable flow controller
• Maximum head height: up to 9.5m
• DC motor for efficient operation
• Feed mode for temporary flow pause
• Quiet running design
• Compact pump footprint
• Suitable for freshwater and marine aquariums
• Suitable for ponds, sumps and circulation systems
• Includes controller and power supply

Adjustable Flow Control

The included controller allows you to adjust the pump output to suit your setup.

This makes it easier to balance water flow through:

• Sump systems
• Aquarium return lines
• Pond filtration
• Water features
• Large freshwater aquariums
• Marine aquariums

You can reduce or increase the flow without needing to replace the pump.

Feed Mode

The controller includes a feed function that temporarily pauses or reduces water flow.

This is useful during feeding because it helps stop food from being pulled straight into filtration or pushed rapidly around the aquarium.

Once feeding is finished, normal flow can be restored through the controller.

High Flow for Large Systems

With a maximum output of 16,800L/H, the DC-18000 is designed for setups that need strong water movement.

It can be used as:

• An aquarium return pump
• A sump pump
• A pond circulation pump
• A filtration pump
• A water-transfer pump
• A water-feature pump

Actual flow will reduce as head height, pipe length, fittings and restrictions increase.

Quiet DC Motor

The DC motor is designed to provide strong output with lower operating noise than many traditional high-flow AC pumps.

This makes it suitable for aquariums and indoor setups where pump noise is an important consideration.

Compact Design

Despite its high flow capacity, the DC-18000 has a relatively compact footprint.

This makes installation easier in sumps, filter chambers and pond systems where space may be limited.

Installation Tips

For best performance:

• Use pipework that matches the pump outlet
• Avoid unnecessary bends and restrictions
• Keep the intake clear of debris
• Allow easy access for cleaning
• Check head height before installation
• Clean the impeller regularly

Flow rate will always reduce as water is pumped higher or through restrictive plumbing.

Maintenance

Regular maintenance helps keep the pump running quietly and efficiently.

Disconnect the power before cleaning, then inspect the impeller and intake for:

• Algae
• Debris
• Sand
• Snails
• Calcium buildup

Keeping the rotor and intake clean helps maintain strong flow and reduces strain on the motor.
