At first glance it is really difficult to choose between these five Tsurumi trash pump choices but here are some differences to pay attention to.
The first two ½ HP Tsurumi trash pumps operate automatically. Whereas the last three Tsurumi pumps are manually operated.
The Tsurumi Pump HS2.4S model is the manual version of the automatic HSZ2.4S model. Currently, the price difference is only about $50. So, just buy the automatic and save yourself a lot effort monitoring a manual Tsurumi trash pump.
When you jump to the ¾ HP pumps they are both manually operated. Of course, you can add a separate on/off water level sensor to make any pump into an automatic pump. Depending on your situation that may not be needed.

The Two Different Automatic Tsurumi Trash Pump Float Systems
First, the Tsurumi HSZ2.4S model has the standard tethered float ball. They work well and they are adjustable. So, you can set the On and Off water levels to where you need them.
However, you do need enough space for the tethered float to operate within without being restricted.
Second, is the Tsurumi Pump HSE2.4S model that has an Automatic Relay Switch instead of the tethered float ball. This pump is only for use when there is a constant water supply. It is for when the pump is intended to run continuously.
2 Inch Tsurumi Trash Pump Applications
- Residential, commercial, and industrial wastewater and site drainage. These pumps are well-suited for handling wastewater in various settings. Whether it’s residential sewage, commercial drainage, or industrial effluents, the HS, HSZ, and HSD pumps efficiently move water containing sand, solids, and various types of trash.
- Decorative waterfalls and fountains. If you’re designing water features like decorative waterfalls or fountains, these pumps can play a crucial role. Their semi-vortex impeller design allows them to handle suspended particles while maintaining reliable performance.
- Raw water supply from lakes or rivers. Need to extract water from natural sources like lakes or rivers? The HS, HSZ, and HSD pumps can efficiently draw raw water for various purposes.
- Sediment removal from small sumps or basins. When dealing with sediment buildup in small sumps or basins, these pumps come in handy. Their agitator feature ensures effective suspension and removal of sediments.
Features Of The 2 Inch Tsurumi Trash Pump Choices
As a group these Tsurumi pump choices are quite similar. So, let’s take a look at the specifications of the HS, HSZ, and HSD series Tsurumi trash pump choices. Here’s a breakdown of the key details:
- Impeller Design:
- These pumps feature a semi-vortex urethane rubber impeller which also has an agitator that can stir up sediment and pump it out. This design permits the pumping of all kinds of trash plus sand and mud.
- Motor Characteristics:
- The pumps are equipped with a continuous-duty copper-wound motor. The motor is surrounded by air which makes it longer lasting than oil filled motors.
- The motor has class E insulation, which permits the motor to run at higher temperatures than Class A insulation that other motors are made with. That means the motor is likely to last much longer than other pumps.
- Sealing and Durability:
- Mechanical seals featuring silicon carbide faces are utilized in pairs within an oil-filled chamber, ensuring both durability and efficient sealing.
- The pumps are equipped with high-temperature C3 ball bearings that are double-shielded, permanently lubricated, and rated for a B-10 life of 60,000 hours.

The first time I helped to install a drain tile and basement sump pump system was 1978.
Since then I have worked for a city water utility where I worked with and maintained pumps.
My rental properties and personal homes all needed sump pumps.
As a modular home dealer/builder, those new homes needed sump pumps.
I put that experience to good use by providing reliable, useful, and practical advice on buying, using, and maintaining sump pumps.
