Design Features

Intelligent Variable Speed Pumps

Armstrong PiB 4380 IVS pumps are the next generation in variable speed pumping, offering the element of built-in intelligence in a motor mounted VFD. The IVS pump is pre-programmed with Sensorless control technology that senses the energy input to the pump and automatically adjusts the speed to the demand of a pre-set system control curve. The IVS controller provides the operating cost savings of a traditional variable speed system, without the added installation expense and complexity of a remote pressure sensor. It is the first true plug-and-play intelligent pump on the market, available only from Armstrong

Direct Replacement

PiB 4360 & 4380 pumps are available with standard NPT connections and ANSI 125 flanges, bronze impellers and standard JM/JP/56C motors with common electrical configurations. The wide array of connection sizes, impeller diameters and motors allow for a simple and direct replacement of almost any pump.

IVS Retrofit

Existing constant speed pumps can seamlessly be upgraded to a PiB 4380 IVS, in systems with 2-way control valves. Simply install the PiB 4380 IVS into the pipeline with the same installation method used for constant speed pumps. Expensive modifications to your current piping system or building structure are no longer required to minimize operating costs. An integrated keypad makes it easy to adjust the pump head to match the system demand and instantly maximize your energy savings. No specialized technicians, remote system sensors or other complex electronic devices are required.

Efficiency

Mechanically sealed pumps provide far greater efficiency compared to canned rotor designs. This design feature reduces power consumption and energy costs.

Versatility

For applications such as boiler recirculation, heat exchangers, chilled water recirculation or cooling tower pumps, the PiB offering has models and sizes to meet your need. PiB IVS models offer the benefits of variable-speed operation and can also serve constant-speed applications by running at a pre-selected speed.

Quality

Armstrong VIL pumps have been installed in thousands of applications all over the world and have demonstrated high performance, consistent efficiency, and maximum durability. The Armstrong Type 2A mechanical seal has a Silicon Carbide stationary seal which makes it one of the most reliable seals on the market today.

Ease Of Maintenance

Since the PiB Series is based on current proven Armstrong commercial pumps, replacement parts are readily available. All PiB Series pumps include industry-standard mechanical seals, ensuring quick and economical service. In the event of regular scheduled maintenance, downtime is minimized. All VIL units can be serviced without disturbing the pump casing.

Intelligent Variable Speed

The Pump-in-a-Box (PiB) DE 4380 and DE 4300 is a true plug-and-play intelligent variable speed pump. It's the smart solution you've been waiting for, responding quickly to changes in system demand. Unlike most systems, which are programmed for peak demand, IVS units provide only the flow and pressure a building actually needs at any given time. The energy savings can pay for the initial cost of the pump in less than a year. And the best part? It's available NOW. Place your order and you can have it at your jobsite within 72 hours or less.

Here's how the PiB IVS works:

Pump performance curves are pre-programmed into the IVS sensorless speed controller. During operation, the power draw and speed of the pump are monitored, enabling the controller to establish the hydraulic performance and position the pump's head-flow characteristic to meet the system requirements. The controller ensures trouble-free operation under all conditions. Incorporating the pump hydraulic data into the controller and removing sensors results in true integration of all components and removes the risk of sensor failure.

The PiB IVS is ideal for variable flow, single operating pump systems. For constant flow applications, pre-set the PiB IVS to a reduced speed and open the throttling valve for improved energy savings.
