The LQRY-A vertical oil pump/vertical hot oil pump maintains reliable operation regardless of the fluid’s high vapour pressure, large proportion of low-boiling fractions or tendency to creep.

Pump features:

• Highly effective venting contour ensures optimum venting.
• Confined gaskets
• Reinforced discharge cover design and optimised heat barrier. This means less heat is transferred to the bearing bracket.
• Double mechanical seal for reliable operation with all thermal oils
• Anti-seize carbon plain bearing lubricated by the fluid handled
• Reinforced deep-groove ball bearing with special grease fill for a long service life
• Optimised shaft contour ensures reliable removal of leakage.

Top energy efficiency is ensured by:

• Optimised hydraulic system yielding high efficiency
• Impeller trimmed to match the specified duty point
• Variable-speed operation in combination with standard IE2 motor

Easy to service, many variants

The thermal oil pump is particularly easy to service due to:

• Replaceable casing wear rings
• Bearing brackets which are straightforward to dismantle

LQRY-A is also available with double mechanical seal and SiC bearings to achieve an even higher operating reliability.
