Seal-less Triplex pump
The new ‘T’ Series of seal-less high pressure diaphragm pumps developed by Wanner extends the company’s unique Hydra-Cell pump concept into higher flow and pressure capacities, where it will compete directly with conventional triplex piston plunger pumps in applications up to 170 l/min and 310 bar.
First of the series to be developed, the T8045, deliver liquid flows up to 170 l/min at 207 bar.
Hydra-Cell’s T Series was originally conceived to handle severe pumping applications in the oil and gas industries. Accordingly, field trials have been conducted chiefly in oilfields, where conditions can be particularly demanding. Required levels of performance, the mix and types of liquids pumped, the working environment and the location (often remote from service facilities) together present a formidable challenge.
In an initial application of the T8045, Wanner is working in collaboration with jet pump manufacturer JJ Tech. The Hydra-Cell pump is at the heart of a volume jet lift process in which it delivers ‘power fluid’ at pressure from surface level to the patented down-hole lift pump. There it is mixed with ‘produced fluid’ (typically a harsh mix of water, particulate debris, oil and gas) and driven to the surface. The combined fluids are then separated and produced water is reinjected underground, completing the cycle.
Other projected applications in oil and gas and in the process industries generally are likely to be similarly demanding – requiring sustained high performance, often in difficult conditions, with such factors as reliability, safety, energy efficiency and minimal downtime paramount.
