Do You Need to Pump Underground Wastewater High and Far? Criteria for Selecting the SFA Sanicubic 2 GR HP S High-Lift Grinder

This product features two pumps that operate alternately, and when the inflow increases, both pumps run simultaneously. It is designed to grind wastewater using Pro X K2 grinding technology and discharge it through an outer diameter 50mm discharge pipe.

Where is the Sanicubic 2 GR HP S needed?

If any of the following conditions apply, you should consider a high-lift grinder wastewater pump.

• Sites where wastewater must be pumped from underground restrooms up to the public sewer at a higher elevation
• Commercial buildings, restaurants, or small commercial facilities where multiple sanitary fixtures are used simultaneously
• Sites with long horizontal distances to the wastewater pipe and high vertical lift requirements
• Situations with large instantaneous wastewater inflow that a single pump cannot reliably handle
• Sites where operation must be maintained with one pump even if the other stops
• Cases where installing a large-diameter natural drainage pipe is difficult and pressure piping is necessary

SFA recommends this product as a dual-motor lifting station for wastewater pumping in large houses, apartments, stores, restaurants, and small commercial facilities.

Key Performance Comparison Table

The above figures represent the maximum technical specifications disclosed by SFA.

The maximum lift of 18m and maximum flow rate of 19㎥/h are the peak points on the pump performance curve, so it does not mean both can be achieved simultaneously in actual field conditions. Actual discharge volume must be calculated considering vertical height, horizontal distance, pipe diameter, number of elbows, and piping resistance.

How does it differ from a standard wastewater pump?

Can a high-lift product be installed unconditionally?

Not necessarily.

Choosing a product based only on maximum lift can result in insufficient flow in the field or selecting a product larger than necessary. You must also check the following conditions together.

1. Vertical height from pump installation location to final wastewater pipe
2. Total horizontal piping length
3. Actual diameter of the discharge pipe
4. Number of piping accessories such as elbows and check valves
5. Number of connected sanitary fixtures such as toilets, sinks, and showers
6. Maximum simultaneous users and instantaneous inflow volume
7. Single-phase power supply and breaker capacity
8. Vent pipe installation location and diameter
9. Availability of maintenance space and inspection openings
10. Purpose of installation and expected daily operation frequency

What information should I provide for model review?

When consulting MyPump, please provide the information below so we can review the model suitable for your actual site conditions.

At MyPump, we do not simply recommend products with the highest maximum lift; instead, we comprehensively review vertical lift, horizontal distance, pipe diameter, user count, and number of sanitary fixtures to determine the actual operating point and guide the appropriate model.

Especially if the lift of existing wastewater pumps is insufficient or single pump operation is unstable in underground restrooms, commercial buildings, restaurants, or multi-use facilities, please consider the SFA Sanicubic 2 GR HP S high-lift grinder dual wastewater pump as an alternative.
