Pump and Pumping System

Whole blood pumping with a microthrottle pump.

We have previously reported that microthrottle pumps (MTPs) display the capacity to pump solid phase suspensions such as polystyrene beads which prove challenging to most microfluidic pumps. In this paper we report employing a linear microthrottle pump (LMTP) to pump whole, undiluted, anticoagulated, human venous blood at 200 μl min(-1) with minimal erythrocyte lysis and no observed pump blocka...

Solar Water Pumping System

PV array is increasingly employed for water pumping system. In this paper, the developed boost converter steps up the voltage produced by the PV array to a value which is suitable to run a single-phase induction motor. The inverter converts DC to AC is controlled by using sinusoidal pulse width modulation (SPWM) technique. By using a LCfilter the harmonics are eliminated and pure sine wave is o...

Venturi-based Two-layer Microfluidic Pumping System

This paper reports a new microfluidic method for pumping fluid and the generation of droplets and bubbles using the Venturi principle, driving flow using pressure without numerous connections or extensive external control systems. The 2-layer devices in PDMS have no moving parts, and can pump fluid at flow rates >

Transparency pump intensity and differential gain in resonantly pumped W optical pumping injection cavity lasers

Title: Development of a Smart Pumping System

In today’s global economy, process plants are under constant pressure to reduce costs. Users can no longer afford their attempts to make pumps bulletproof by upgrading component specifications. The development of a smart pumping system was fostered by a challenge from a major chemical user to reduce the total cost of pump ownership. A smart pumping system was successfully developed that can rea...
