Pumpability tester

• 

Product Introduction

The pumpability tester is dedicated to accurately testing the pumpability of the shield tail seal grease used in shield construction. It is an integrated and innovative instrument and equipment of China Railway No. 5 Institute combined with American standards and domestic capillary rheometer. The equipment is made by Changchun Intelligent and used in Beijing Railway No. 5 Institute, with good overall use. At present, the equipment has been used in the polymer laboratory of China Railway Construction in South China. The scale use of the equipment greatly improves the overall performance of the domestic shield tail sealing grease, and provides an effective testing equipment for the further development of the product.
