Closed Impeller Chemical Processing Pumps Packing Seal Pump for Hydrofluoric Acid
Features
1. Heavy duty volute casting with integral foot and multi-ribbed discharge flange provided superior resistance to pipe loads and improves reliability back pullout design allows for removal of the rotating element without disturbing the casing pipe work of motor to simplify routine maintenance.
2. Impeller: Duplex stainless cast, an open impeller for high-efficiency performance, low running cost and long life, impeller back vanes and shroud design provides axial balance which reduces maintenance and downtime cost by extending seal and bearing reliability.
3. Pump Casing: Top centerline discharge, self-venting casing, arranged for back pull-out. Fully confined gasket. Foot support under casing for maximum resistance to misalignment and distortion from pipe loads. ANSI B16.5, 150# flanges standard and also ANSI B16.5, 300# optional for working pressures to 2550 kPa with 3mm corrosion allowance. For maximum corrosion / erosion resistance casing is supplied without tapped openings but if specified, gauge and drain plug openings are provided.
