The SPLT split-case pump is a single-stage centrifugal pump with a horizontal split casing and double-suction. According to the Masdaf catalogue, the series has a flow rate ranging from 30 to 4,500 m\u00b3\/h, a head ranging from 15 to 180 m, and a speed ranging from 1,000 to 3,600 rpm. The pump is designed for liquids with temperatures up to 110 \u00b0C and is used where large volumes need to be pumped at moderate head.<\/p>\n

What does a horizontal chassis connector mean?<\/strong><\/h2>\n

The casing is divided by a plane passing through the shaft axis. The upper half can be removed, giving full access to the rotor with its impeller, wear rings and bearing assemblies, without the need to disconnect the pipework or move the motor. The inlet and outlet flanges are aligned on the same axis, so the pump can be installed in a straight section without transition bends. For a stationary pumping station operating for decades, this is the main practical advantage of this design: scheduled maintenance does not require dismantling the pipework.<\/p>\n

Why have a wheel with a double-sided entry?<\/strong><\/h2>\n

The fluid is fed to the impeller from both sides. Due to the back-to-back configuration, the axial forces from the two halves of the impeller balance each other out, and the shaft does not require a unloading device. A second benefit is the increased total inlet cross-section: at the same flow rate, the inlet velocity is lower, so the series has a low NPSH and operates where suction head is limited. The catalogue specifically highlights the enlarged impeller inlet, which smooths the flow and reduces noise.<\/p>\n

\u00a0How to interpret model codes<\/strong><\/h2>\n

The notation is based on the following scheme SPLT 65 \u2013 250<\/code>, where SPLT is the series designation, the first number is the nominal diameter of the discharge flange in millimetres, and the second is the nominal diameter of the impeller in millimetres. In other words, the SPLT 65\u2013250 has a discharge flange of DN 65 and an impeller with a diameter of 250 mm. With this logic in mind, the pump\u2019s name on the nameplate immediately reveals both the connection type and the hydraulic size.<\/p>\n

The standard version is designed for clean and process water. For more corrosive environments, the flow path is available in stainless steel; the bronze wear ring remains standard in all versions, as it is this component that bears the brunt of wear in conjunction with the impeller.<\/p>\n
