Model D

Model D pumps are single-stage, centrifugal, bronze-fitted design for applications with temperatures typically 200°F or less. However, higher temperatures are possible depending on specific operating conditions. Pump types (such as 106-D, 110-D, etc.) selected depends on the design operating conditions—flow rate, discharge pressure and NPSH requirements; impellers trimmed to operating conditions. Model D can be flange-mounted (Model DF) either vertically or horizontally (Model DH). Vertical mounting saves floor space and avoids dirt and water. Pump can also be fitted with a threaded suction adapter flange for in-line applications (DFT).

Equipped with industry standard motors available in single or three-phase at either 1750 RPM or 3500 RPM. Pumps are furnished with bleed lines, sometimes called seal flushing lines, to help prevent the pump from vapor binding and to allow pump operation against a dead shut-off for a period of time without burning seals. Standard mechanical seals provide for temperatures up to 250°F. Higher temperature seals and special faces available upon request.

An optional isolation valve for installation in the suction piping is available to quickly remove the pump for repair and maintenance without draining the receiver and saving labor costs.
