Multiquip 1803100130 Volute 205S - OEM Replacement Part for Centrifugal Water Pumps

The volute is the spiral-shaped housing component in centrifugal pumps that converts the kinetic energy from the rotating impeller into pressure, directing water flow from the suction inlet to the discharge outlet. This genuine Multiquip volute is engineered specifically for QP205 series high-pressure centrifugal pumps, designed to handle maximum pressures up to 100 psi and flow rates up to 106 gallons per minute.

When a volute becomes worn, pump performance deteriorates significantly. Common symptoms include reduced discharge pressure, decreased flow rates, and difficulty maintaining prime. According to Multiquip troubleshooting procedures, worn volutes should be replaced alongside impellers to restore optimal pumping capacity and prevent impeller binding issues. The volute works in precise clearance with the impeller—improper clearance causes binding and makes the pump hard to start, requiring shim adjustment or component replacement.

This volute is compatible with the following Multiquip pump models:

• QP205SB (Vanguard 160 5.0 HP Engine)
• QP205SH (Honda GX160 Engine)
