CPT Type Marine Ejector Pump | Perpendicular Suction for Tight Spaces
A heavy-duty ejector pump featuring a right-angle structure. The suction flange sits perpendicular to the pump body axis. This design solves installation challenges in restricted spaces where fluid direction must change. It handles mixed liquids and solids reliably.
Accreditation and Certificates:
The CPT Type pump distinguishes itself through its structural layout. Unlike the coaxial CPJ model, the CPT features a suction flange axis that is perpendicular to the pump body axis. This creates a distinct right-angle flow path.
This design is specifically engineered for complex installation environments. If your ship’s piping layout requires a turn or if axial space is too limited for a straight-line pump, the CPT is the better choice. It uses a high-pressure jet to create a vacuum, drawing fluid in from the side. It retains all the robust mixing and transport capabilities of standard ejectors but adds critical flexibility for layout planning. It is ideal for retrofitting in crowded engine rooms or specialized dredging setups.

Key Features：
- Right-Angle Design: Suction flange is perpendicular to the body axis.
- Space Adaptability: Fits where straight-line pumps cannot.
- Directional Change: Naturally alters fluid flow direction by 90 degrees.
- Clog Resistant: Handles sewage, sludge, and dredging materials.
- No Moving Parts: Low maintenance and long service life.
Applications：
- Restricted Space Installation: Bilge pumping in crowded machinery zones.
- River Dredging: Sucking up sand where piping requires angles.
- Sewage Treatment: Moving waste fluids with flexible piping.
- Powder Conveying: Transporting industrial powders in complex layouts.
Installation & Maintenance：
Installation: The working water inlet and discharge are on one axis, while the suction connects from the side (90 degrees). Check flange alignment carefully.
Maintenance: Inspect the nozzle for wear. Since the flow turns, check the impact area in the chamber for abrasion over time.
Custom Options Available：
We offer custom flange standards (DIN/JIS/ANSI) to match existing ship piping.
FAQ ：
Q1: What is the main difference between CPT and CPJ?
A1: The CPJ is coaxial (straight-line) for maximum efficiency. The CPT is perpendicular (right-angle), designed for limited spaces or where the fluid direction needs to change.
Q2: Which one should I choose?
A2: If you have plenty of space and want the best flow rate, choose CPJ. If installation space is tight or pipes need to turn 90 degrees at the pump, choose CPT.
