Positive Displacement Pump Applications: Case Histories 

CIVIL PROTECTION

Dense slurry pump: Completing what the hydro pump cannot

The Tarua ® dense slurry pump delivers an innovative solution for sludge management in flooded environments. Working alongside the hydro pump, Tarua ® completes the job by extracting the last few centimetres of water, dense sludge, and debris — all with a single operator.

BUILDING SECTOR

Water and sand suction pump for construction sites

The Tarua ® water and sand suction pump is used in the construction industry for efficient management of water, sludge, and debris during foundation piling, well drilling, construction excavation, and tunnel drainage.

CIVIL PROTECTION

Mud suction pump for flood response

FOOD INDUSTRY

Surface grease extraction pump for equalization tanks

The Tarua ® volumetric pump demonstrated exceptional suction capacity in this application. Working from a 6-metre drop, it extracted only the 5–10 cm surface layer of concentrated grease from an equalization tank and transferred it to a storage tank 30 metres away.

ENVIRONMENT AND TERRITORY

RIVER BED CLEANING PUMP

With the TARUA® reciprocating pump, riverbed cleaning was possible by continuously sucking up mud, sand, and debris without any protection such as filters or grinders.

SEWAGE PLANT

High-density mud pump for sewage plants

Using the TARUA ® sludge pump, very dense sludge was sucked up to a depth of 5 m and transferred to an above-ground settler at a height of 8 m.

PAPER INDUSTRY

SLUDGE PUMP FOR CLEANING EQUALIZATION TANK

The equalization tank has a depth of 4 m; the sludge composed of pulper and biological material was sucked in and transferred directly to thesludge dewatering plant DRYBOX ® PLUS with in-line conditioning and mixing possible with the sludge pump TARUA ®.

Water and silt suction pump for reservoir maintenance

Thanks to its suction capacity, Tarua® extracted very fine silt from the reservoir bottom, leaving the water clear without disturbing the water volume or interrupting operations.

WELL CLEANING

Full-passage pump for stones, rags and debris

Everything that enters the suction pipe passes through the pump body without clogging. Tarua® handles stones, rags, bolts, clamps, and other solid objects typically found at the bottom of industrial sumps and tanks.

Positive displacement pump examples across industries 

Tarua ® is engineered with full-passage technology, allowing it to handle fluids containing solid particles — including sand, sludge, debris, and organic matter — without risk of clogging. This makes it one of the most versatile positive displacement pump examples in the industrial market, suitable for chemical, food processing, ceramic, aquaculture, and environmental applications. Its robust construction ensures reliable performance even in extreme operating conditions.

Real-world positive displacement pump applications: significant examples

Among the most significant positive displacement pump applications documented in our case histories is industrial waste management. In an environmental remediation project, Tarua ® was used to extract sludge and sewage from a settling tank where conventional pumps had proven ineffective — handling both liquids and high-density solids without clogging.

In the food industry, Tarua ® has been used to transfer olives and tomatoes without damaging the product. At critical stages of the production process, the pump maintained full product integrity — demonstrating its suitability for delicate material handling applications.

In the ceramic industry, Tarua ® replaced an outdated pumping system in a major manufacturing facility, handling clays and abrasive materials continuously. The result was a significant improvement in production efficiency and a substantial reduction in maintenance downtime.

Self-priming pump applications in emergency and industrial contexts

The versatility of Tarua ® self-priming pump applications extends to emergency response. During flood events, the pump has been deployed to extract large volumes of water mixed with debris, operating reliably in critical conditions where speed and continuity are essential.

Tarua ® is available in multiple configurations, adaptable to the specific requirements of each industry and application. A key advantage is its ability to operate in dry-run mode — continuing to function safely in the absence of liquid without sustaining damage, a critical feature in unpredictable field conditions.

Across all sectors and positive displacement pump applications documented inthese case histories, Tarua ® — by IDEE E PRODOTTI — has consistently proven its value as a robust, flexible, and high-performance solution for handling both liquids and solids. Its full-passage design, self-priming capability, and multi-sector track record make it a benchmark in industrial suction pump technology.
