Pump Applications

Don’t worry our pumps have been used in the brick and mortar industry. More to follow soon™

The L-Series peristaltic pumps are happy pumping a wide variety of chemicals all day long. This includes sticky highly viscous products that need transferring to sheer sensitive products that need to be handled delicately and everything in-between.

Peristaltic Pump Advantages:

peristaltic-pump-tick-smallWear as a result of abrasion from hard solids or chemical attack is mitigated as a result of everything being self-contained within the hose element which is an issue with most pump types especially where rotating elements come directly into contact with the product.

peristaltic-pump-tick-smallFlow rate drop off as a result of fluctuating viscosity levels is a minor concern compared to other pump technologies such as AODD pumps (Air Operated Diagram) or centrifugals as capacity and efficiency will remain constant.

Peristaltic pumps are ideal for industrial / mining sludge and slurries due to their simple design, superior solid handling, suction lift and run dry capabilities. Industrial slurries have claimed the life of many a poorly selected pump, the combination of pumping product that is highly abrasive, typically contains solids north of 70% by weight and specific gravities (SG) far greater than that of water can result in frequent and expensive maintenance overheads or worse still replacing the pump altogether.

Mining or shaft drilling transfer applications commonly want to move as much slurry as possible in the shortest amount of time which means utilising our 4” and 6” pumps, the L100 and L150. With hard solids clearance of up to ~22mm and soft solids clearance of ~ 120mm, peristaltic pumps have the added benefit of drastically reducing water wastage on transfer duties as suspension levels can be lower.

Our pumps are equally as comfortable when used for reagent dosing applications that contain highly corrosive chemicals such as sulphuric or hydrochloric acid used in processing the likes of copper, cobalt and gold.

One of the more common uses of our peristaltic pumps is as primary sludge pumps within Waste Water Treatment Works or Plants (WWTWs / WWTPs) with the typical entry point being the L50 and scaling all the way up to the L100. By virtue of the pumps design the lack of any rotors, glands, seals or valves to block or wear will often result in a reduction overall service and ultimately life costs.

Peristaltic Pumps: WWTW Dosing Applications

On the smaller end of the scale our L10,L15 and L25 are ideal for accurate (± 0.1%) dosing and metering applications that typically involve pumping the likes of caustic soda, polymers, sodium hypochlorite (“hypo”), powder activated carbon (PAC), lime or ferric chloride.

peristaltic-pump-tick-smallIn most instances the use of our peristaltic pumps negates the need to macerate the product prior to being pumped in order to avoid ragging which is a common solution associated with progressive cavity pumps.

peristaltic-pump-tick-smallIn dosing applications sodium and calcium hypochlorite (“hypo”) tends to off-gas when pumped which can result in vapour-locking in diaphragm pumps.

peristaltic-pump-tick-smallSalt solutions (also common in water softening processes) can prevent valves from closing which can lead to the pumps running dry. Internally there are no valves to close within a peristaltic pump and it’s quite happy to run dry until the cows come home.
