Why has the YOKOTA Suction Pump been chosen?
YOKOTA Suction Pumps, the largest type in our Enhanced Self-Priming Pump (PAT.) series, are outfitted with all the necessary equipment in a modular design that facilitates transfer to the construction site. The mud, sand and earth siphoning main pump is connected directly to the bleed pump (vacuum pump) to discharge air mixed in the pump. Both are set up on a base plate with the operation control panel. As for conventional pumping devices used in the past for the reverse circulation construction method, mud, sand and earth penetrating the vacuum pump caused damage or pump stoppage. However, mud, sand and earth do not penetrate YOKOTA Suction Pumps because they are equipped with a “continuous bleeding mechanism” (Intl. PAT.). As a result, assured, continuous operation is possible without breakdown or pump stoppage. Moreover, based on this “continuous bleeding”, excellent suction efficiency provides continuous, safe operation even at suction head of -8 meters. This is the main reason why
