Our range of Diamond Series Progressive Cavity Pumps is characterised by a modular design covering numerous models and sizes, enabling capacities up to 110 m³/hr and discharge pressures up to 48 Bar.
The Diamond Series was designed and built with high modularity in mind. This means that each element of the pump can be specifically selected based on the application requirements. So, even if the product-use varies over time, the product can be adapted and upgraded to renewed process specifications. As a result, a plethora of combined options and accessories enable progressive cavity pumps that can be easily tailored to almost any site requirement.
The JN and DN Diamond series is an ideal solution for use across the industrial sector in pumping a vast range of fluids. Each pump in this series offers reliability, high performance capabilities and flexibility across a number of applications. Designed according to the strictest standards, they comply with the requirements of standard API 676 typically used in the offshore oil & gas industries, which are synonymous with high performance, reliability and robust design.
These pumps are suited to pumping viscous and non-viscous products, with or without solids of any nature.
The entire JN & DN Series can be ATEX certified upon request.
DN Series
The DN Pump Series is the basis for which all pumps within the close-coupled series are routed. Robust cast casings characterise them in numerous materials, large inspection ports, multiple sealing and connection options, and a wide array of stator and rotor materials.
JN Series
Tapflo use a modular design for their pump manufacturing, and the JN pumps are used as the basis for all pumps with bearings within the Diamond Series. Other pump ranges within the series have modular “bolt-on” features. The JN Pump Series is very similar to the DN Pump Series but has a more robust design due to it featuring a separate bearing housing.
It is also more suited to high pressure and high viscosity applications when compared with the DN Series. The JN Series requires a larger installation space, and DN Series units can be upgraded to JN Series units thanks to the modular design of the Bearing Lantern Bracket, which can be simply plugged onto the drive side of the DN Series.
JN Progressive Cavity Pumps can be manufactured from a range of materials, and boast features such as:
- Large inspection ports
- Numerous sealing & connection options
- A wide array of stator & rotor materials
