Pumps DHSB-JHSB Diamond Series


Diamond Series DHS-B (with module B)

PROGRESSING CAVITY PUMPS

Hopper Industrial Series

Series with hopper an auger feed screw to convey directly the product to hydraulic part, are the ideal machines for pumping viscous and non-flowing, with a very high solids content.
The DHS e JHS series are the hopper rectangular version with increased auger feed screw to the hydraulics.
Suitable to pumping non flowing product up to 40% of dry that tend to create bridge or blocks that shut out, is particularly useful in the pumping product that tent to deform under load (pseudo plastic behavior) .
The auger feed screw integrates a special device for joint protection.

 

  • DHSB series: the drive is coupled directly to the pump via a flange. This solution is extremely cheap and compact, considerably reducing installation costs and simplifying maintenance. The stress generated by the hydraulic part is supported by the drive itself. Each drive used is adequately selected based on their specific technical parameters and are subject to numerous duration tests with heavy loads.

DHSB DIAMOND SERIES

 

  • JHSB Series: the drive is connected to the shaft inlet via a coupling joint. This configuration is the best solution in terms of performance and durability. All the stress generated by the pump is absorbed by the bearings in the housing. These bearings have very high resistance against loads. They are assembled with extreme precision on the highest quality manufactured parts. It is the best solution when you want to guarantee duration and reliability, yet with greater installation space requirements. The bearing housing designed by us is modular and can be installed after a pump with the DHS series block housing. It is state of the art for this type of installation.

<strong>Patented Pin Joint:</strong>

The pin-type joint, the actual heart of the single screw pump, is the best solution of its type on the market. It offers greater duration, reliability and reduced maintenance costs, managing to combine extreme compactness with unrivalled strength. Its particular manufacturing enables the sub-division of axial loads and torque in different elements, making it one of a kind. As well as the above, replacement of worn parts is cheap thanks to the bushes in the worn zones, avoiding costly replacement of parts (rotor, drive shaft, and female drive shaft. To resist high pressure in the pump casing up to 12 bar, the pin can be hydraulically balanced.

<strong>Base plates:</strong>

The base plates, characterized by considerable thicknesses are very strong. Available in carbon steel or stainless steel. They can also be provided according to standard API 676, in a trolley version, with anti-vibration housing or on skids, according to the client’s specifications.

<strong>Materials:</strong>

The parts in contact with the product of the DN and JN Diamond Series pumps can be manufactured in various materials. From the version in cast iron to stainless steel (AISI 304 and AISI 316), as well as other materials on request such as Duplex and Super Duplex. Also, in the version in cast iron, the rotating parts are still manufactured in stainless steel AISI 420 or on request in AISI 304 / AISI 316.

<strong>Low pulsating flows:</strong>

Tensional stress and pulsating flow are very low. The centrifugal effect is reduced to a minimum thanks to the low operating speeds and mainly the axial development of the pump.

<strong>Shaft sealing:</strong>

Different sealing systems can be installed, each solution being suitable to specific usage. The types available are: mechanical seal, single outer mechanical seal, single mechanical seal with quench, back to back double mechanical seal and double mechanical seals in tandem, Packing seal and flushed packing seal. The sealing systems are all interchangeable on the standard pump. Each solution was carefully engineered while taking into consideration  all the operating conditions. As well as changing the sealing system, you can also install various types of mechanical seals based on the application. The compartments are suitable for installation of the seals manufactured according to the standards ISO EN 12756. As well as this, it is possible to use cartridge seals from the main manufacturers, also available according to standards API 682 category 1.

<strong>Modularity: </strong>

The Diamond series is based on the concept of modularity in every characteristic: hydraulic parts, casing, seals, base plates, housing, drive shafts. Each part can be manufactured in a series of variants without changing the structure of the machine, while keeping the main spare parts standard.

<strong>Performance: </strong>

Duration, efficiency, reliability and low consumption. With the Diamond series, we have reached the maximum levels of technological development in every aspect.

<strong>Versatility:</strong>

The Diamond series was designed to be versatile whatever its use. For this reason it can be set up with various options and accessories suitable for every field of application. As well as the above, the peculiar features of the single screw pump are naturally taken advantage of with various types of fluids pumped, from low to the highest viscosity, clean and containing solids varying in size and nature.

<strong>Motorizations:</strong>

Al the drives which are installed on the Diamond series have been tested for long periods and subject to strict and rigorous technical checks. We can install both electric and hydraulic motors.  All the models of reducers and variators present determined characteristics in terms of strength, size of the bearings and the quality of the gears.

 
<strong>Efficiency: </strong>

Maximum performance level, exceptional operating efficiency thanks to the optimum volumetric yield and high pressure and is consumption reduced to a minimum. All the Diamond series hydraulics efficiencies were calculated to guarantee the maximum found on today’s market.

<strong>Quality</strong>

Each part is manufactured according the highly restrictive quality specifications. Finishes and precision of each part are the basis of each pump manufactured. All parts are subject to specific controls based on their characteristics and functionality.

 
<strong>Maintenance:</strong>

  The Diamond series is designed to ensure easy maintenance and normally require the replacement of a minimum number of components. In particular the joint bushes allow the replace of the same without having to replace shafts and rotors. The costs of maintenance are really reduced. The cost of the pump, considered in his full life cycle, is highly competitive.

<strong>Cost / benefit :</strong>

The Diamond series, thanks to the compactness of its elements combined technical success without comparison at very competitive costs. The modularity allows you to make the right  solutions depending on the application to avoid paying for features you do not need, all in favor of its competitiveness.

 
<strong>Self-priming:</strong>

The peculiarities of the hydraulic parts of the progressive cavity pump allow excellent self-priming (up to 7m). The Diamond series were designed to create the minimum loss possible in the pump body, thanks to large sections and a joint compact design and fluid dynamic.

 
<strong>Ease of installation:</strong>

The pumps of the Diamond series are easy to install due to compactness, simplicity of operation and operational flexibility thanks to the various features included.

<strong>Detailed documentation: </strong>

Each pump comes with clear and detailed operating instructions. Orders are followed by experienced and qualified staff that integrates in providing detailed documentation on demand and specific for the product supplied.
