ProPhase® conveying pumps

All ProPhase dense phase vessel assemblies are supplied complete with ProDV Dome Valves on the inlet, outlet and vent positions, electro-pneumatic controls, air management module and instrumentation, pre-wired and pre-piped, ready for connection to electrical supplies and compressed air, nitrogen or CO2.

The inherent simplicity of the ProDV Dome Valve, utilised on all pumps, ensures system reliability and low maintenance operation.

​

1. ProPhase Pump

​

The ProPhase pump, is the standard dense phase pump configuration and is a simple, effective and highly reliable method of conveying material from a single collection point to either single or multiple reception hoppers. It can operate in multiple modes, including batch or a continuous system. Equally suited to transfer either from storage into a process or from a process into storage. 

Systems can operate at temperatures up to 480ºC with throughput rates up to 100 t/hr and distances up to 500 meters. The inherent simplicity of the ProDV Dome Valve, the only moving part in the Qlar dense phase pump system ensures the overall system reliability and low maintenance operation.

​

Used for a range of materials, including 

 

• detergent ingredients 

• alumina

• cement

• nonferrous concentrate 

• fly ash

• gypsum 

• sand

Vessels can be manufactured to most international pressure vessel codes and designed for a working pressure of 7 Barg standard. Special designs are available on request.

• Standard vessel material is Carbon-Steel, with coatings and Stainless-Steel grades available on request 

• Pumps are free-standing, special foundations are not required.

• Available with PhasiQ controller or can be controlled by plant PLC 

• ATEX-compatible versions are available on request

2. ProPhase D

​

The D Pump is Qlar’s unique, self-adaptive Dense Phase Pneumatic Conveying solution. It was developed to overcome the challenges when conveying problematical materials, that have an inconsistent material density, due to variations in the source of supply.

​

The D Pump works in conjunction with a unique Qlar pipeline system that is self-regulating and provides a closed feedback loop to the controller of the pump and valves. The ProDV Dome Valve, which forms an integral part of all Qlar pneumatic conveying and injection systems, partially closes when required – the control system constantly measures and controls the flow of material to generate a smooth conveying line pressure. This solution is adaptive to the material in the pipeline and enables the control system to cope with any changes in conveying pressure. 

​

Systems can operate at temperatures up to 480ºC with throughput rates ranging from 200 t/hr and distances up to 1000 meters. The inherent simplicity of the ProDV Dome Valve (the only moving part) in the Qlar ProPhase D Pump system ensures the overall system reliability and low maintenance operation.

3. ProPhase TD Pump

​

The ProPhase TD Dense Phase Pump is a batch transfer vessel, similar in concept to the Standard Dense Phase Pump, with improved capability for large tonnages and longer distance conveying, designed for fine fluidizable materials. 

Throughput rates increased to 250t/h and distances up to 1500 meters with optimum conveying over 600m. Systems can operate at temperatures up to 480ºC. 

The ProPhase TD Pump has the lowest air consumption, per ton conveyed, in the range and is designed to minimize material degradation, by utilizing the slow transfer velocities of dense phase conveying.

The inherent simplicity of the ProDV Dome Valve, the only moving part in the Dense Phase Pump system ensures the overall system reliability and low maintenance operation.

4. Ash handling pumps

​

To provide the most effective pneumatic conveying system for ash handling requires a range of pumps and pressure vessels for the Power and Heavy Industries.

​

The range of pumps available from Qlar are as follows:

• Multi PD Dense Phase Pumps

• Multi Dense Phase System

​

Multi PD Dense Phase Pumps

The Multi PD Pump is designed for handling either fine or coarse fly ash from ESPs or from bag filters and can be used to convey directly to the main silos without using an intermediate hopper. There can be up to 8 pumps connected on the same pipeline with an ESP. The most efficient arrangement is for the vessels to be connected across the gas stream of the ESP so that each vessel receives approximately an even loading. No level probe is required in the ESP when using the Multi PD pump system

​

The Multi-PD pump system is able to convey distances up to 750m and at higher conveying velocities than with multi Dense Phase vessels. The Multi-PD system also has lower specific air consumption and utilise smaller pipe sizes to achieve the same conveying rate as a multi Dense Phase system.

​

The Multi PD pump assemblies are supplied complete with Dome Valve, electro-pneumatic controls and air supply piping, strainer, pressure regulation and control equipment pre-piped and pre-wired ready for connection to isolated air and electric supplies and connection to a suitable vent pipeline.

​

Multi Dense Phase System

Originally developed in the 1970’s for the power industry, the Multi Dense Phase System has been advanced to reliably handle a wide variety of ash from economisers, air heaters, electrostatic precipitators and waste incinerators. The Multi Dense Phase System is a simple, effective and highly reliable method of conveying ash from single or multiple collection points to either single or multiple reception silos. The Dome Valve being the only moving part in the vessel ensures system reliability and low maintenance operation.

​

Even with its low height Multi Dense Phase Systems are capable of operating at temperatures up to 480ºC with throughput rates of up to 100 t/hr and distances up to 200 metres. Originally designed for conveying of fly ash from multi outlet precipitators or bag filters on powers stations, the same Multi Dense Phase technology can be used with other materials in other industries where material is to be conveyed from multi outlet precipitators, bag filters or multiple feed points.
