Many years after their introduction, Tsurumi Pump has just lately seen an increased demand for its computerized moisture-sensing pumps. This article appears on the KTZ and KTV dewatering models.
The e-probe KTVE range comprises 4 fashions starting from 85-220 gal/min, at head requirements as much as 85 ft.
According to Tsurumi Pump, dewatering pumps that includes electric probes that detect rising water ranges to forestall dry running are rising in popularity in the building and industrial market with an elevated demand for this kind of automated know-how. Although the corporate has produced these pumps for several years, quite a lot of elements corresponding to product enhancements, rising vitality costs, labour shortages and the elevated urge for food for the benefits that the technology can provide imply Tsurumi is now gearing up to meet an anticipated rise in demand throughout North America.
Tsurumi’s KTZE and KTVE series pumps, for instance, take the performance of its KTZ and KTV fashions and improve them by way of the incorporation of a durable, fixed-position stainless-steel probe on the pump head cover, related to an inside relay unit.
How the e-probe works
When this e-probe comes into contact with water or different conductive media, a signal is sent to a timer. If the contact lasts for more than one second, a steady low-voltage electrical circuit is shaped between the probe and the pump body, acting as the ground, prompting the relay to change on the pump. Once the water degree has receded beneath the extent of the probe, the pump will continue to operate for an additional 60 seconds before shutting off, reducing the prospect of short cycling as a outcome of potential turbulence within the water, and stopping the pump from running dry.
By stopping unnecessary dry operation, damage on the put on and tear components is minimised, extending the lifespan of the pump. “This makes these pumps ideal for any dewatering utility where an operator isn’t current to manually turn them on and off in accordance with water levels,” mentioned Mike Klimes, purposes engineer at Tsurumi. “To enable automatic operation, you’d typically have to utilise a tether float switch, suspension probe, or strain transducer in addition to an computerized management panel.”
Instead, the Tsurumi models use the far simpler and cheaper approach of a moisture-sensing electrode management device, thereby enabling the pricey automated management panel to get replaced with a a lot easier guide panel, bringing an immediate price saving that is soon followed by important vitality financial savings because of the shorter working time.

As properly because the financial benefits, an important factor within the rising adoption of these solutions is how the e-probe technology enhances the robust and sturdy nature of the pumps to which they’re connected. Unlike a design relying on tethered float switches, the robust probes do not stick out beyond the pump’s footprint and are due to this fact at little danger of damage. This enables them to simply stand up to the inevitable rough handling at the job site as they are unloaded from a truck to the ground and then on to the final location.
“These pumps are frequently lowered down pipes that present entry to deep underground for dewatering,” Klimes explained. “External cables would usually get tangled up in that state of affairs, however that’s not an issue when you’re using electrode pumps. Also, when you’re in a decent house, floats don’t always work very well, and erosion can cause a build-up of debris that will make them even much less effective. All of that can have a negative effect on the lifespan of the pump, so our electrode solution guarantees tremendously improved effectivity and fewer downtime total.” A probe cover will quickly come as standard with these pumps, eliminating the possibility of the electrode being broken during transportation or severe-duty operations.
Designed to last
With a durable cast iron physique, the KTZ sequence is designed for the most demanding purposes and is easily convertible between high-pressure and high-volume configurations. It features high-chrome impellers to withstand the extremely abrasive liquids found in construction, aggregate and mining applications, whereas twin silicon carbide mechanical seals are isolated within the oil chamber to guard the seal faces from abrasion and corrosion. The KTZE moisture-sensing variant is on the market on fashions between 2-5 hp, handling 110-385 gal/min at head requirements of up to eighty two ft.
Offering a weight saving of approximately 25 lbs over forged iron pumps, the compact, wear-resistant KTV fashions have been designed for light- to medium-duty functions. Their slimline die-cast aluminium body and elastomer pump finish provide easier dealing with. A semi-vortex impeller allows for max particle passage size while offering extended parts life. The want for impeller effectivity adjustments has additionally been eradicated, and the pumps are immune to calcium carbonate deposits.
The e-probe KTVE vary includes four models starting from 85-220 gal/min, at head necessities up to 85 ft.Other Tsurumi pumps incorporating the expertise include the HSE and LBA fashions, and the forthcoming LSCE range.“These e-variant pumps mix all of the brawn of their normal siblings with a intelligent probe that can turn them on and off automatically,” Klimes concluded. “The effective automation they supply can be extraordinarily useful in a variety of applications.”
Top advantages
To conclude, the main benefits of Tsurumi’s e-probe pumps embrace the avoidance of dry running, a design that’s robust and sturdy to resist tough dealing with and transporting, there is not any want for a more expensive computerized panel and the pumps are appropriate for job website dewatering the place pumps are left unattended. The pumps additionally prevent failures and so save the pump’s motor, the probe is inside the pumps exterior diameter, it suits into tight spaces where floats don’t work well and there are not any external cables. All of this means much less downtime and an enchancment of general efficiency.
