SB6×5×11 离心式砂泵
砂泵主要是用来为除砂器、除泥器、泥排量和压力的钻井液。经过十多年的现场 应用和改进，本公司研制的离心式砂泵，无论在技术性能方面，还是在密封寿命方面均局国内领先水平，并达到国外同类产品的水平。
该泵有电动和皮带驱动两种形式。根据客户特殊要求可提供新的设计产品。
Sand pump is used to provide drilling liquid with a certain discharge capacity and pressure to desander, desilter and mud pump. The centrifugal sand pump developed by the company through over more than ten years of site applications and improvements is in the domestic advanced level, either in technical performance or in sealing life, and reaches the same level as the similar products abroad.
The SB8×6×14 centrifugal sand pump applies to over 3000-meter-long drilling rigs; The SB8×6×11 centrifugal sand pump applies to under 3000-meter-long drilling rigs,also can be can be used to supply mud to triplex mud pump as a filling pump. The SB6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or pocket drilling rigs; The SB4×3 centrifugal sand pump is usually used as measuring pump or replenishment pump; he SB4×3 centrifugal sand pump is usually used as clean water pump
The pump has two types of drive, electromotion and belt drive. New products can be designed and provided according to customers’ special requirements .
