Design Features
The Fybroc series 1500 pump is designed for broad corrosion-resistance through the use of high quality materials and state-of-the-art engineering. Its simplicity and versatility make it the ideal choice for all demanding pumping requirements.

The fiberglass components are manufactured utilizing the Resin Transfer Molding technique which enables complete control of the fiberglass reinforcement in high stress areas. Metallic pump components are NOT in contact with process fluids.

1. ANSI/ASME B73.1 Conformance ensures maximum interchangeability with existing metal ANSI pumps, thereby eliminating any need for piping or foundation changes when up-grading an installation to Fybroc Series 1500 pumps.

2. Smooth Hydraulic Passages promote increased pump effiency.

3. Single One-Piece Gusseted Casing easily withstands the rigors of normal plant piping loads.

4. Impeller Pump-Out Vanes and relief holes minimize axial unbalance and lower stuffing box pressure.

5. Alloy Insert (integrally molded with impeller) with rounded edges carries impeller torque load with low stress.

6. Versatile Casing Cover is suitable for use with most single outside or double inside mechanical seals without modification.

7. Continuous-Strand Fiberglass Construction for all wetted parts in either vinyl ester or epoxy resin provides maximum corrosion resistance for a wide range of difficult liquids.

8. Casing Through-Bolts maintain casing o-ring seal integrity under all hydraulic operating conditions.

9. Integral Shaft Sleeve design eliminates gaskets and o-rings and protects the pump shaft from exposure to the process fluid.

10. Large Capacity Bearings ensure operating life will in excess of the minimum specified by ANSI/ASME B73.1.

11. External Impeller Adjustment allows field setting of impeller-to-casing clearance.

12. Heavy-Duty Shaft minimize deflection to maximize mechanical seal life.

13. Polyester Thermosetting Powder Coated Power Frame
components prevent external corrosion.

14. Labyrinth Oil Seals nickel plated-bronze for longer life. Improved oil containment.

The Series 1500 pumps have been designed to maximize the life of bearings and mechanical seals which can deteriorate because of shaft deflection resulting from radial thrust. Radial thrust is the force acting on the side of an impeller as a result of the non-uniform distribution of pressure around the pump casing at off-peak operation.

The magnitude of this thrust varies with the flow, but the amount of radial thrust can roughly be cut in half by utilizing a double volute casing. The solid line in the chart to the right depicts the typical radial thrust characteristic of a single volute casing. The dotted line portrays the use of a double volute casing and the resulting reduction in radial thrust.

The drawing at lower right shows the location of the “cut water” in volute casings. The cut water is close clearance extension of the casing located at the base of the volute. Also, shown in orange, is the second cut water of “splitter” used in the double volute casing, which channels half of the flow to the pump discharge. The splitter reduces of-peak flows and reduces both radial thrust and its resulting shaft deflection. Fybroc uses double volute casing in eleven of its larger pump sizes where, typically, radial thrust loadings are higher. See chart on Casing Data, Volute.
