AY high temperature multistage centrifugal oil pump

A horizontally mounted, segmented multistage centrifugal oil pump engineered for high-head, high-temperature petroleum transfer and industrial process services. The AY series is a restructured successor to the Y series, optimized for improved energy efficiency and modernization of rotating equipment.

Key features

• Multistage centrifugal design delivers high discharge head in a compact footprint; impeller stages are configurable to meet required head.
• Horizontal pump body with upright suction and discharge flanges; pump casing supported on a horizontal base for straightforward installation.
• Suitable for clean petroleum products and other liquids without solid particles.
• Wide performance envelope: capacity range typically 6.25–180 m3/h and head range typically 105–657 m (model-dependent).
• Operating temperature range: commonly specified from 0 up to ~300 °C (confirm exact rating for each model/trim).

How to read model codes (example: 40AY-35*12)

• 40 = suction flange internal diameter (mm)
• AY = series designation (centrifugal oil pump)
• 35 = single-stage head (m)
• 12 = number of impeller stages

Typical applications

• Crude oil and refined petroleum transfer
• Petrochemical and chemical process feed lines
• High-head boiler feed and other industrial oil-handling services

Notes for procurement

• Select model and stage count to meet required flow (m3/h) and total head (m).
• Verify material options, shaft sealing arrangements, flange standards, and temperature/pressure ratings against your process conditions before ordering.

Contact your supplier with required flow, head, fluid properties and temperature to receive detailed dimensional drawings and performance curves for the selected AY model.
