|||||||||||||
ManufacturingFICEM PLDa series self-priming electric pumps are monobloc pumps with a horizontal shaft, an incorporated check valve and direct coupling to the motor. The pump body and the impeller are made of cast iron with a considerable thickness, the latter having two wide open channels in order to offer the greatest possible space for passing bodies and is cantilevered to the shaft. The pumps are equipped with a three-phase asynchronous electric motor (single phase up to 2.2 kW), with external fan cooling, IP55 rating, class F insulation, 2RS oversized, self-lubricating ball bearings. The pump shaft is connected to the motor directly, without joints, reducing vibration to a minimum. The whole range is available with pipe thread connections for quick coupling to the system piping, preventing any dripping or leaking of liquids. The electric pumps use an unbalanced mechanical seal, supplied by a leading Italian manufacturer. For special projects, it is possible to supply PLDa series electric pumps with a double automatic sealing device, housed in a chamber containing liquids or solids, which also prevents any accidental leaks of fluid from the pump body. Materials (standard version)
Mechanical sealTwo types of unbalanced mechanical seal are available: Type 3 Type 5 Mechanical seal specifications
Specific mechanical seals are available for liquids containing suspended abrasive particles. ConnectionsThe whole range of FICEM PLDa pumps is available with pipe thread connections and, on request, PN16/40 threaded or weld-on counter flanges and sets of nuts, bolts and gaskets are supplied AdjustmentIn order to adjust performance on the basis of requirements, it is possible to use the PLDa series pumps, connecting them to control systems which provide continuous performance adjustments based on needs. The maximum rotation speed is set at 3500 rpm. Product features and advantagesOptimised hydraulics Highly efficient motors Ease of maintenance Anti-corrosion treatment and final painting
