The pressure chamber is a volute body pump, the radial force in the deviated from the design conditions is calculated as follows: FR = 1000KHD2B2 where FR-radial force, N; H-head, m; D2- impeller outlet diameter, m; B2- impeller outlet width (including the thickness of the two covers), m; K-radial force coefficient, can be obtained by the following formula: K = 0.36 [1- (Q '/ Q) 2] Where Q- design flow; Q '- Actual traffic. When the pump is running under design conditions, according to the above formula to find the radial force coefficient is equal to zero, zero flow when the radial force coefficient is the largest, that is, K = 0.36. The size of the coefficient K also depends on the pump type, in some cases , The actual value of K is greater than that obtained from the above formula, and K may reach 0.6 at zero flow rate.

The registered trademark name, Hastelloy, is applied as the prefix name to more than twenty different highly corrosion resistant metal alloys produced by Haynes International, Inc. Thesesuperalloys, or high performance alloys, developed by Haynes International, are nickel-based steel alloys that exhibit traits that include high resistance to uniform attack, localized corrosion/oxidation resistance, stress corrosion cracking resistance and ease of welding and fabrication.
Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternatives to the various Hastelloy® brand alloys.
The corrosion-resistant superalloys are widely used by the chemical processing, aerospace, and industrial gas turbine and marine industries. Additionally, due to the their reliable performance, areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries are increasingly using them.
