MP Series Industrial PumpThe MP Series Industrial Pump is a heavy-duty S-valve piston slurry pump used to convey fluids with a high viscosity.Operating Procedure and Working PrincipleFor example in a canal dredging project the pump is mounted on a pontoon next to an excavator. The slurry is loaded into the hopper of the pump. In the hopper the slurry is mixed by a hydraulic driven mixing device. The slurry is sucked by the vacuum created by the retracting cylinder. When the cylinder is fully retracted the s-valve switches to the other cylinder and the full conveying cylinder will press the slurry through the s-valve into the pipeline. The basic principle is the same as seen on most concrete pumps. In this field the S-valve pumping system has proved to be highly reliable and the best suited for high viscosity and abrasive fluids.The slurry is pumped to the shore through a pipeline with an inside diameter of 250 mm.Application: Dredging, Wet Mining, Bio MassThis pump system is primarily designed for river or canal dredging. The slurry can be loaded into the hopper of the pump by an excavator. In most cases it is not necessary to add extra water so the slurry can be conveyed in a high density which is one of the main advantages in comparison to other options such as a centrifugal pump. When the slurry is pumped to a lagoon on shore there is no water return flow. In many EU countries permission for return flow at dredging projects is needed. The slurry will dry fast, and for example can be transported by truck with very low water content within several weeks.Main Features of the MP Series Industrial PumpHigh outputs up to 200m3/h on a short distance, to meet capacity of 30 to 45 ton excavatorsCapable of pumping slurry with a low water contentNot sensitive for foreign objects in the slurry with sizes up to 150 mmVery good wear resistanceOriginal western diesel engines like Deutz, Volvo, Caterpillar, Perkins etc.High quality hydraulic and electrical componentsClosed structure design realizes friendly relationship with the environmentSales office with experienced staff located in Rotterdam, The NetherlandsSpare parts warehouse and well trained service engineers available 365 days a year in RotterdamPower Pack SystemSingle or twin engine designExtra hydraulic pump and proportional valves for other external functions like spud winchesThe power pack can be delivered as an open skid to be mounted in a ship, or with a canopyOptionally the power pack can be installed in a 20ft container providing substantial noise reduction and easy transportation possibilitiesHydraulic SystemHeavy duty open loop hydraulic circuit design for continuous operationLarge size suction and return filtrationHigh-quality hydraulic components (Rexroth; Vickers)Electro-proportional control of the main hydraulic piston pumpDamping and oil-compensation valves mounted on the hydraulic cylinder for smooth operationHigh quality, high speed seals used in the hydraulic cylindersControl systemLocal control on a control panel, and by a reliable HBC remote controlDigital engine panel with extensive information about fuel consumption, torque, speed etcAll electronic components of the system controlled by a Siemens S7 PLCReliable OMRON solid relaysVarious warning indicators for easy troubleshootingPump unit Wear parts made from wear resistant materials like Tungsten, long lasting and easy to replaceLarge diameter conveying cylinders with a long stroke provide good suction performanceHeavy duty, reliable S-valve swing systemAuto adjustment of clearance between S valve and wear board guarantees continuous good sealingAutomatic retraction of conveying cylinder piston, for easy inspection and maintenanceAll greasing on the pump unit by a reliable hydraulic controlled automatic greasing system
