Conventional non-clog centrifugal pumps often experience issues where the impeller and the water-cutting section become jammed or collide with the outer wall, leading to damage to the contained objects in the liquid or causing entanglement accidents, due to the spiral shape of the impeller rotation chamber. In contrast, the Spurt NZL pump can be considered a revolutionary centrifugal pump that addresses these defects. For more details, please download the catalog.

The completely self-priming pump "for acid resistance, abrasion resistance, high concentration slurry, and high-temperature liquids" received the 2nd Science and Technology Agency Commissioner Award in 1982 and the 5th Invention Award <Invention Contribution Award>. The models available are SPF type, SPS type, and SPA type. Patent No. 1177214. Registered design No. 561657, No. 546920. For more details, please download the catalog.

The usage example is for Company A (a chemical company in Chiba Prefecture). The pump model is SPF-100, and it has been in operation for approximately 26 years. The fluid name is wastewater pit sludge. The purpose is to suck up the sludge and transfer it to the treatment tank. In detail, from the suction points in a pit of about 100m² (a total of 6 points), one pump self-primes up to -2m to the liquid surface and transfers it to the treatment tank beside the pit. The number of suction points can be adjusted based on the amount of sludge accumulation, allowing for suction from one point at a time or simultaneously from two or more points, with adjustments made via the valves in the suction line.

The semi-self-priming pump "for acid resistance, abrasion resistance, high concentration slurry, and high-temperature liquids" has received the Science and Technology Minister's Award, the 5th Invention Award, and the Contribution Award for Inventions. It transports high-concentration liquids and high-viscosity liquids that could not be conveyed by conventional vortex pumps, as well as slurry liquids that would wear out with positive displacement pumps, all without any liquid leakage. For more details, please download the catalog.

The "spiral slurry pump" is a pressure-fed (non-self-priming) pump, and since the mechanical seal is installed on the suction side, it does not experience pressure (back pressure) within the casing even with an outside configuration. Therefore, the sliding surface pressure of the mechanical seal remains stable, preventing seal leakage. For more details, please download the catalog.

• Other pumps

It enables the delivery of high-concentration and high-viscosity liquids that exceed the limits of a vortex pump by utilizing strong vacuum force (-760mm/Hg) generated by the swirling flow directed towards the impeller, without any seal leakage. *Liquids without fluidity are not acceptable. For more details, please download the catalog.

**Features** ◆ Compact Design The casting weight is designed to be as light as possible, making it more affordable to use high-quality metals such as Hastelloy and Carpenter in the wetted parts. ◆ No Seal Leakage Since the shaft seal (mechanical seal) is installed on the suction side, even with an outside configuration, it does not experience casing internal pressure (back pressure), ensuring stable mechanical sliding surface pressure and no seal leakage. ◆ Compatible with High Concentration and High Viscosity Liquids Due to the absence of seal leakage and strong suction power, liquid transfer under pressure is possible. ◆ Full Liquid Drainage with Vacuum Operation *For more details, please contact us.*

【Features】 ◆ Designed for high pressure Considering turbulent wear caused by slurry, the impeller is not multi-stage but has a larger diameter in a single stage to increase circumferential speed and boost pressure. ◆ Ideal for applications requiring high pressure maintenance In cases like filter press injection or cyclone injection, a stable high pressure is necessary, so a seal leak-free spur pump is suitable for automatic operation without pressure fluctuations. ◆ Self-priming capability It has a semi-self-priming structure, so while there are limits to the suction lift, it can self-prime. *For more details, please contact us.

• Other pumps

【Features】 ◆ Continuous and intermittent slurry self-priming pump This pump has a structure that allows water to accumulate in the pump body, eliminating the need for a self-priming tank. However, the amount of air in the suction side piping can be self-primed up to about 80% of the water in the pump body. Beyond that, self-priming will require additional water to be added. *Due to limitations on suction lift and the inability to re-prime after sucking in air, it is referred to as a semi-self-priming type. ◆ Rubber lining specification available Designed for acidic liquids such as hydrochloric acid containing slurry, considering corrosion and wear resistance. ◆ No seal leakage Since the shaft seal (mechanical seal) is installed on the suction side, even with an outside method, it does not receive casing internal pressure (back pressure), ensuring stable mechanical sliding surface pressure and no seal leakage. ◆ Compatible with high concentration and high viscosity liquids Due to the absence of seal leakage and strong suction power, it is capable of pumping under both suction and pressure conditions. *For more details, please contact us.

• Other pumps

**Features** ◆ Capable of transporting solid objects It can transport contained objects in their original form without causing damage. Depending on the impeller shape (as described below), it can transport all contained objects that pass through the inlet without damaging them and without clogging inside the pump. For example, if you put something in a pipe and shake it, it will fly away due to centrifugal force. This is the principle of this pump. ◆ Wear resistance Not damaging solid objects also means that the pump itself will not be damaged. ◆ Self-priming capability It can be self-priming if a self-priming tank and suction pipe are installed. However, some impeller shapes may not allow for self-priming. In that case, a self-priming assist device will be added. *For more details, please contact us.*

• Other pumps

Due to the vertical structure, the impeller is mounted horizontally at the bottom, making it resistant to air (it can also operate with mixed liquids or intermittent air suction). Additionally, it can suction and transfer slurry liquids.
