Let us get deep into the design section of Armstrong 4360 and 4380 close coupled vertical In-line pumps.

Series 4360

Iron Casing

This is designed to make maintenance easy. It comes with a radically split cast iron casing that allows removal of the pump rotating assembly and motor without causing disturbance to the pump casing. The casing is hydrostatically tested; working pressure 140* F and ideal for 175 psig.

NPT threaded flanges

The entire pump can be removed from the line when required since there are NPT threaded companion flanges that come along with the pump.

Mechanical seal

There's a mechanical seal inside with Silicon Carbide seat that can be effortlessly serviced without breaking the pipe connections. The mechanical seal is a single spring with resin bonded ceramic and carbon faces. Each minute detail is attended to and made to service and maintain easy.

Flush and vent connection

The flush and vent connections are made to remove entrained air and make sure the liquid is at seal face all the time.

Equal discharge and suction

The discharge and suction connections are equal; this has enabled the simplification of piping design. This has also made possible easy installation and service.

Enclosed Impeller

A fully enclosed pump impeller is in place. It is secured by stainless steel fittings to the pump shaft.

Bearing free

Armstrong 4360 close coupled vertical In-line pump design comes with no bearings. You will be pleased with fewer lifecycle costs.

Series 4380

Durable motor

The face mounted motor adheres to the industry standards. The make is superb and assures lasting service to the user.

Flush and vent

The flush and vent connections remove entrained air and ensure liquid is at seal face all the time.

Mechanical seal

Mechanical seal, a single stainless steel piece on the inside with Silicon Carbide Seat is made to service and maintain easy without removing the pipe connections. There's a bronze shaft sleeve that extends to full length of the mechanical seal space.

Motor and pump with 360⁰flanges

Sturdy and secure union of motor and pump with the heavy and strong cylindrical bracket that comes with a 360⁰ flange on either flange is another notable feature.

Dynamically balanced impeller

The bronze, pump impeller guarantees a smooth operation. It is fully enclosed and designed to be dynamically balanced to prevent vibrations. This feature is among the very sought after when buying pumps.

Cast iron casing

Series 4380 has a split cast iron casing and equal discharge and suction flange sizes. There are tapped separate openings for flush, drain and gauge connections. The pump casing is hydrostatically tested; working pressure 140⁰F and ideal for 175 psig. The casing gasket is appropriately confined to adhere to the strict industrial temperature and pressure applications.

Straightening vanes and passageways

Efficient suction performance and noise free operation is made possible by broad inlet passageways and vanes.

Ribs cast

Ribs cast come integral to casing. The surface aligns with the floor support to avoid misalignment.
