HZT029015001 15MBD Marine Vacuum Sewage Pump (Compatible with JETS Marine Sewage Vacuum Toilet Systems)

I. Product Overview

The HZT029015001 15MBD marine vacuum sewage pump is a high-performance vacuum pump designed specifically for sewage and graywater systems on ships and offshore platforms.

The pump integrates vacuum creation, sewage crushing, and discharge functions. It utilizes a stainless steel, corrosion-resistant structure and a high-vacuum impeller system.

It maintains long-term stable operation in humid, high-salt, and highly corrosive marine environments.

This model is fully compatible with mainstream international vacuum toilets and sewage treatment system interfaces, such as JETS and EVAC.

It can directly replace the original equipment and is suitable for system retrofits, component replacements, and OEM applications, without the need for additional piping adjustments.

II. Product Features

1. High Vacuum Efficiency and Strong Suction Design

The high-vacuum negative pressure chamber instantly establishes stable suction, enabling rapid sewage and graywater extraction in long pipelines. Vacuum efficiency reaches up to 85%, ensuring continuous and stable operation of the vacuum toilet system.

2. Built-in Dual-Knife Shredder System

Integrated rotating and fixed blades (models HZT029150400 / HZT029150500)

Effectively shred paper, fibers, and debris, preventing clogging. This core component of the ship’s sanitation system.

3. All-Stainless Steel Pump and Motor Coupling Structure

The pump casing, pressure chamber, suction chamber, and impeller are all constructed of 316 stainless steel,

providing excellent corrosion and impact resistance. Directly coupled to a high-protection marine motor (IP55), it produces minimal vibration and noise.

4. Compact Structure and Easy Maintenance
The suction chamber cover (HZT029150310) and rotor housing (HZT029150800) feature a quick-release design.

Maintenance and replacement of the shaft seal (HZT038201500), O-ring (HZT037219210), or flap valve (HZT029151001) do not require complete unit disassembly.

5. Strong System Compatibility
Both the vacuum and discharge ports support a variety of interface specifications, fully compatible with the JETS 15MBD and 15MB series.
This makes it suitable for retrofitting and component interchangeability upgrades of marine sewage vacuum systems.

III. Working Principle

The HZT029015001 vacuum sewage pump generates negative pressure within the vacuum chamber.
Sewage from vacuum toilets or graywater tanks is drawn into the pump body, where it is crushed by the blade assembly and discharged as a mixed stream before being transported to a sewage treatment plant or collection tank.

The unit integrates vacuum generation, wastewater transportation, and impurity crushing.
It can operate continuously at negative pressures of 0.6 to 0.8 bar.
Combined with a vacuum valve, vacuum controller, and graywater recovery unit, it forms a complete marine vacuum exhaust system.

VI. Maintenance and Spare Parts

The HZT029015001 is designed for long-term, maintenance-friendly operation.
Core wearing parts include:

Rotor (HZT029150701)
Shaft seal assembly (HZT038201500)
Flap valve base (HZT029151001)
O-ring (HZT037219210)
Cutter assembly (HZT029150450)

All parts are individually replaceable, and HZT offers a full range of accessories and repair technical support.

Regular replacement of the shaft seal and O-ring ensures long-term stable vacuum performance.

VII. Compatibility

The pump body dimensions and flange connections of this model are identical to those of the JETS 15MBD series,

allowing for “drop-in” replacement in ship sewage system renovation projects.
It fully matches the EVAC series in vacuum performance and flow parameters,
supporting mixed use or complete system replacement, and has been successfully verified in multiple shipyard projects.

VIII. System Advantages and Value

Energy-saving and high-efficiency: The vacuum system has a low starting load, reducing energy consumption.

Strong anti-clogging performance: The double-blade crushing structure ensures continuous operation.

All-stainless steel corrosion protection: Extends equipment life and reduces maintenance frequency.

Global standard interface: Compatible with mainstream systems such as JETS, EVAC, and HDT.

Excellent engineering compatibility: No modifications are required to the ship’s piping or foundation installation structure.
