Centrifugal Pump KOSHIN KTH/KTM Series (Made in Japan) centrifugal pumps mounted engine, Honda and Mitsubishi. A large water pump to withstand heavy use. Designed and manufactured for use in construction and civil engineering in particular. Take care and maintenance quick and easy. With a maximum power of 3.6 kW – 7.1 kW can be connected to a hose pipe sizes ranging from 50 mm (2 “) – 100 mm (4”).
Conventional mechanical seal using carbon ceramic is replaced by silicon carbide (SiC) seal. SiC seal is developed by Koshin and we are the first manufacturer to use such durable material in Japan.
Special plug designed on impeller allows easy removal. Simply insert any rod and twist to separate impeller from its casing. No special tool required.
Conventional trash pumps are very bulky and heavy, some more than 100 kg in weight. KTR-100X, the largest of all, weights only 81 kg. The compact design takes up smaller space and is portable.
Special structure is designed to ensure high capacity self-priming performance. Koshin trash pumps give excellent performance and durability
