、Design features
The pattern of 2GRN series installation is horizontal.
The 2GRN series pump is that the double layers heat the pump body, it is great to heat the area, the distribution is even. It can heat promptly by body to pump, can make part to be uneven in temperature to produce out of shape so that unusual phenomenon of running etc. Insert a set of  very open hot steam or heat conduction oil and heat the pump.
The twin-spindle screw pump is sealed according to the status of the different options, in order to guarantee the sealed quality of the pump.

NO.3、A few tips on pump selection
1、Please select the appropriate rotational speed in accordance with the viscosity of the liquid, so as to ensure that NPSHr of the pump can meet the practical suction conditions of our customers.
2、If the medium viscosity exceeds the range on the performance table, please contact our technology department. We will always provide you with satisfactory service.
3、After the pump selection, please ask for the measurements of the pump and the electrical machinery unit’s accessories for the basic construction design.
4、Whether we will deploy the safety valve depends on customer’s request and the safety valve only protect the pump for a instant, can not be the overflow valve of conduit.
