When Is A Submersible Pump Necessary? – Allflo Pumps & Equipment

Submersible pumps are widely used across commercial, industrial, rural, and municipal applications. They are commonly selected for handling stormwater, sewage, wastewater, bore water and other fluids where reliability and efficiency are critical.

Their key advantage is operating below the fluid level, allowing them to push liquid to the discharge point rather than pulling it from above ground.

When to Choose a Submersible Pump

A submersible pump is typically required when:

• The pump must operate below ground or below fluid level
• Pit depth or suction limitations make above-ground pumps impractical
• Flooded or confined environments are present
• Reliable priming and continuous operation are essential

Because submersible pumps use hermetically sealed motors, they can operate safely while fully submerged — something surface-mounted pumps are not designed to do.

While submersible pumps are highly versatile, correct selection is essential. Factors such as fluid type, solids content, temperature and operating depth must be considered to avoid premature failure.

Types of Submersible Pumps

Different applications require different submersible pump designs, including:

• Grinder pumps
• Vortex pumps
• Cutter pumps
• Axial flow pumps
• Drainage pumps
• Dewatering pumps

Each type is designed to handle specific flow rates, solids and operating conditions.

Material Selection Matters

In harsh environments involving corrosive fluids, high temperatures or aggressive wastewater, material selection is critical.

For example, Remko 316 stainless steel submersible pumps are designed to resist corrosion and provide long service life in demanding applications. Using a pump outside its intended duty can void warranties and lead to unnecessary downtime and cost.

Choosing the Right Solution

Submersible pumps are not always the answer, but when depth, reliability and operating conditions demand it, they are often the most effective solution.

Allflo Pumps & Equipment can help assess your application and recommend a submersible pump suited to your site conditions, fluid type, and duty requirements.
