Peristaltic hose pump survives sulphuric acid

The LPP peristaltic hose pump has been used successfully in a sulphuric acid process.
The LPP peristaltic hose pump has been used successfully in a sulphuric acid process.
The LPP pumps sulphuric acid to a thickener in which the sulphuric acid reacts as a flocculant.
Very few pumps can reliably handle this medium, and even fewer can provide flexible flow control when a supply tank is on a higher level than a discharge head.
In this application the sulphuric acid concentration is 20-30% at ambient temperature and the slurry specific gravity is 1.3.
The flow rate varies from 0.2 to 0.5m3/h and the maximum speed is 35rev/min.
The pumped flow is controlled by an inverter, the average flow being 9 litre/min.
The LPP is controlled using a PID control loop with fixed set point and feedback from a Krohne Coriolis mass flow meter.
The pump is also equipped with a hose leak detector.
The LPP provides safe and reliable liquid transfer, even when handling the most aggressive media.
The robust construction of the most durable materials makes the LPP resistant to the attacks of viscous, abrasive and corrosive fluids.
The LPP is available in sizes DN 25, DN 40 and DN 65 for a maximum working pressure of 10bar with flow capacities up to 20m3/h.
