Zenit bend unions are made from GFL-250 cast iron or galvanized steel and have UNI standard flanges to guarantee complete interchangeability.
There are 2 types of bend unions: inlet and outlet.
Inlet bend unions + the hydraulic connection to be made to pumps for dry chamber installations.
This accessory was created to sustain the weight of the pump and so that it could be fastened onto the support base.
The outlet unions are designed to be coupled to the pump's delivery port or inside the plants, both of which provide a 90° direction change.
They may be flange-flange or flange-thread type, for maximum versatility.
They provide full free passage. Another advantage is the reduced curvature radius, which allows a lower overall dimension to be obtained with respect to all the other accessories on the market.
Depending on the models, they can be made of GJL-250 cast iron, galvanized steel or stainless steel.
