Flanged Industrial Series
The Vertical series is the ideal solution for pumping from wells or tanks. It is suitable for pumping viscous and non-viscous products as well as abrasive or aggressive ones.
Available with outlet flange connections UNI, DIN, ANSI and GAS BSP; the suction nozzle instead is made with a particular design optimized for priming the product in which it is lost in.
The length is totally customizable according to the setup requirements. The stainless steel version (AISI 304 or AISI 316) has a protective jacket that covers the stator as standard to prevent it from corrosion.
There are two standard configurations availables: the short version and the long version.
The difference is in the length of the installation with which they are required for. The short version is compact, robust, easy to install.The long version instead allows installation in deep wells or tanks, and presents a complete series of dedicated optimizations such as the removable inlet for easy maintenance of the rotor, stator and coupling.
A fundamental characteristic is the support of the downhole baseplate, with a clamping cone which makes the pump very stable and vibration free even in extreme conditions of use.
Both series are always configured in a monobloc arrangement.
- DV Short version: Compact. This version allows installation with only anchor plate.
DV series short
- DV Long version: This version requires to be fixed with a downhole baseplate with the clamping cone to minimize the vibrations and oscillations of the pump caused by the considerable length of the pump itself.

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 durability, 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.
(standard for DV Series).
The parts in contact with the product of the DV 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.
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.
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 seals 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
Duration, efficiency, reliability and low consumption. With the Diamond series, we have reached the maximum levels of technological development in every aspect.
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.
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.
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.
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.
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.
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.
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.
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.
