The unexpected flooding in Germany in the summer of 2021 was a serious test for the Super Heavy Duty


The unexpected flooding in Germany in the summer of 2021 was a serious test for the Super Heavy Duty Trash Pumps Series KTZ from Koshin Ltd. These are the new economy class models of "Made in Japan" motor pumps.


KTZ-80S - series means:

  • K-Koshin Ltd. 70-year-old manufacturer of centrifugal and submersible pumps of traditional Japanese quality;

  • T- Garbage (for dirty sandy and muddy waters with stones up to 20 mm KTZ-50 and 27 mm for KTZ-80 and KTZ-100);

  • Z- (with Koshin gasoline engine);

  • Suction and discharge flange diameters: 50-2 "(50mm), 80 - 3" (80mm) and 100 - 4 "(100mm);

  • H-stands for traditional design

  • S-stands for new design with easy maintenance compared to previous traditional Koshin models.

The KOSHIN self-priming centrifugal debris pump is a unique combination of powerful KOSHIN engine, robust design and reliable performance. This robust large displacement pump is the best choice for the toughest dewatering jobs: construction sites, municipal applications, flood waters and floods.


The main advantage of the new generation of waste pumps of this family is the affordable price, which is about 30% lower compared to waste pumps of the same quality from other manufacturers. The most affordable price for genuine Japanese quality modern KOSHIN K300 and K420 engines is the heart of the Koshin garbage pump, capable of pumping large volumes of waste water without clogging the pump.


The high-tech Koshin design of this HEAVY-DUTY trash PUMP has the following main unique components:

  • Impeller with 2 blades in chromed cast iron;

  • The volute casing is made of nodular cast iron;

  • Silicon carbide mechanical seal.
