Hydraulic submersible sand dredging pump
Hydraulic driven submersible sand suction dredging pump is mainly used as an excavator attachment taking place of grab bucket when there is too much water, mud and not suitable for digging. It is driven by the excavator hydraulic system or a separate hydraulic station to pump sand, sludge mortar etc. Its flow passage components is made of high-strength and wear-resistant alloy.
1. Besides the main impeller, the bottom of the pump is additionally provided with a set of agitation impeller which can spray the deposited sludge into turbulent flow, and therefore the pump realizes high-concentration conveying under the condition of no auxiliary device.
2.The unique seal device can effectively balance the pressure inside and outside the oil chamber, so as to protect the reliability of the mechanical seal to the maximum extent.
3.The motor adopts various protective measures such as overheat protection, water inlet detecting protection, and can operate safely for a long term in harsh working conditions.
