Series 4382

Designed to incorporate two Armstrong standard Series 4380 close coupled Vertical In-Line pumps in a single casing. All existing 4380

series catalogue information and performance curves may be used, or doubled in the case of parallel operation, for the Series 4382

Vertical In-Line pump.

Motor: Industry standard, designed for in-line service.

Flush and vent connection: - Removes entrained air ensuring

lubricating liquid is at the seal faces at all times. Piped to pump

suction.

Mechanical seal: - Inside type with Silicon Carbide seat,

serviceable without disturbing the pipe connections.

Impeller: Dynamically balanced to ensure smooth vibration-free

operation.

Volute: Radially split, with equal suction and discharge flange

sizes. Separate tapped openings for gauge, flush and drain

connections.

Gasket: Confined casing gasket to meet stringent industrial

temperature and pressure applications.

Flapper valve: Hydraulically isolates casings preventing

recirculation when only one pump operates.

Isolation valves: Allow one unit to be isolated and removed for

service while the second unit remains in operation.
