The ERY thermal oil pump conforms to the EN733 (DIN24255) standard design. It incorporates a unique bearing housing design that effectively dissipates heat, achieving in lower temperatures at the surface of dynamic seal and bearings. The pump allows for easy maintenance with its back pull-out feature.

The ERY Series thermal oil pump is specifically designed to handle temperatures up to 350°C in heat transfer without requiring external cooling. It is important to note that the fluids being pumped must possess lubricating properties and should not contain any solid particles or abrasives, as the non-drive end bearing and dynamic seal rely on the pumped liquid for lubrication.

Structural Features of Hot Oil End Suction Centrifugal Pump

• ERY series pumps have single stage, single volute case. It sucks axially and discharges vertically upward.
• There are balancing holes on the impeller vanes that balance the axial force effectively. A line bearing is used on the pump side and a groove ball bearing is used on the coupling side (some pumps use double row angular contact ball bearing at high speed).
• The line bearing is lubricated with the conveyed fluid, the deep groove ball bearing and the double row angular contact bell bearing are lubricated with grease.
• ERY pumps are fixed with dynamic seal devices and the cover is uniquely designed, with the addition of separating effect of the split-floe device. The temperature at the dynamic seal can withstand up to 150°C, ensuring a safe seal and operation in transferring hot oil.
