The Family series can also be used for residual water with an optional adapter.

With its compact design and low weight, our Family can be quickly moved to where it is needed to pump out standing down to the smallest residue. This is made possible by a rubber adapter that is inserted into the suction strainer. This brings the suction point closer to the ground. This allows the pump to pump out water down to a residual height of 1 mm. Ideal for use on construction sites, in underground garages, on flat roofs and in basements.

New concepts in tunnel construction require the concrete used there to have a fire protection effect itself. This is made possible by the addition of plastic fibers, which reduce or prevent explosive concrete spalling.

However, the addition of plastic fibers to the shotcrete inevitably leads to blockages in the pumps: in the pump housing, impeller and inlet strainer - and thus to increased wear.

However, this is not a problem for pumps from the LH series, for example. Their seals have pressure relief openings. These form a flow path above the pump housing, allowing to drain out of the pump and away from the shaft. This protects the mechanical seals from excessive pump pressure or water hammer in high head applications.

The pressure relief openings therefore prevent blockages in the hydraulic area of the pumps. This reduces the costs for cleaning and spare parts. Should a blockage nevertheless occur, the pressure relief openings can be cleaned quickly and easily in a few simple steps.

During a construction site training course, we introduced the tunnel construction company's employees to the function of the pressure relief openings and trained them in handling the pumps.

In the last few weeks we have already presented two of three affinity laws for pumps. These laws are about how it affects the pump performance by the changes in the operating conditions of a pump. By calculating the delivery flow rate, delivery head (pressure) or speed in relation to the pump performance, you save yourself complex tests on the construction site.

The third law of affinity, which is the topic today, also makes your work easier. Use the simple formula to calculate the ratio of power consumption to pump speed.
The power consumption is directly proportional to the cube of the ratio of the pump speeds. So if you double the pump speed, the power consumption increases by factor of eight (assuming all other factors remain constant).

Today we are concluding our short series on the FSP with an exciting video:
In it, our technical experts show you how the FSP consists of a submersible pump, jet injector mechanism and three floats. Find out how you can easily adjust the suction opening so that the scum is extracted with a minimum amount of water.

We take a special look at the jet mechanism. This ensures stable operation, even when water, air and floating scum are sucked in at the same time. In the video, we show you exactly how this works and in which applications the FSP series impresses with its great reliability. Have fun with it:

🔎 Feature Friday - Built to Be Forgotten

Courtesy of Tsurumi Pumps UK Limited

Reliability is not proven on day one.

It is proven over time.

At the University of Nicosia, a test sewage treatment plant was used to trial new wastewater treatment concepts under challenging conditions, including raw sewage with braided solids.

The requirement was simple.

Pump continuously.
Avoid clogging.
Maintain performance.

Two Tsurumi 100C43.7 cutter pumps were installed.

What followed was unexpected.

They ran for over eleven years.

No maintenance.
No intervention.
No clogging.

The system kept running.
So the pumps were forgotten.

Only during a major construction project did performance begin to change. Large volumes of sand entered the system, increasing abrasion and wearing down internal components.

Even then:

⚙ No major mechanical damage
🛠 Only wear components affected
📈 Core performance remained intact

The insight is clear.

Reliable equipment reduces the need for constant attention.
It allows operations to focus elsewhere.

But it also highlights an important balance.

Reliability supports stability.
It does not remove the need for maintenance.

Because even the most robust systems operate within limits.

The difference is how long they sustain performance before those limits are reached.

That is where engineering matters.

Last week you got to know the FSP here on this channel during its use in Austrian construction. These floating scum separators collect floating sludge and other impurities on the water surface and return them.

The position of the inlet can be freely selected by adjusting the float. This means that the height between the water surface and the inlet remains constant even when the water level fluctuates.

At the pump outlet, a bypass circulates part of the pumped water and creates a jet of . This jet injector mechanism promotes the suction process and ensures stable suction, even when water, air and debris are sucked in at the same time.

As the FSP series is equipped with a semi-open impeller, solids can be conveyed efficiently.

A hydroelectric power plant was built in Austria. In order to drive the turbine, a 20 km long had to be bored. This required numerous pumps to remove the water produced.

The water was pumped into a water treatment plant for purification. However, a graphite film was then discovered floating on top of the water. This discovery halted the entire project as the water treatment plant was not designed for graphite separation. The engineers found out that the graphite film came from the drilling process, as the material was in the rock. A solution had to be found for the separation of water and graphite in the treatment plant: our FSP!

The FSP removes impurities from the water surface. Like all Tsurumi pumps, this unit is also equipped with double mechanical seals so that they are as standard. This allowed the customer to operate the FSP for several months without any problems or maintenance until the graphite had disappeared.

The compact LSCE2.75S pump from the LSC series has an excellent reputation with customers. It drains water down to a residual moisture content of 1 mm and is therefore often used in flooded basements.

The 750 watt motor of the new LSC2.75S has plenty of power for a greater maximum delivery head of 17 meters. This means that the pump sucks up debris from places that are deeper in the ground and further away from the pump than ever before - with a delivery rate of up to 228 litres/minute.

This model in the LSC series also prevents the sucked-in water from flowing back when the pump is switched off. The flow-through design of the easy-to-operate, maintenance-friendly pump ensures forced cooling of the motor and thus enables hours of continuous operation at low levels.

Last week we presented the first of three affinity laws for pumps. These laws are about how changes in the operating conditions of a pump affect its performance. By calculating the flow rate, head (pressure) or speed in relation to the pump performance, you can avoid complex on-site testing. Instead, you can use the 2nd affinity law to calculate the delivery head from the comfort of your desk.

This law shows that the ratio of the delivery head (pressure) is directly proportional to the square of the ratio of the pump speeds. If you double the pump speed, the head (pressure) will increase fourfold if all other factors remain constant.
