MMVP mobile marine vacuum pumps

LIMIT PLUS Ltd. Has produced and offers a mobile vacuum pump MMVP, the only one in the world produced completely out of stainless steel (INOX AISI 316). Suction of sewage is based on vacuum (underpressure) technology, and the tank has the volume of 350 or 500 liters.

The MMVP pump is placed on a trailer with independent electric drive enabling its moving much simpler, independently from forklift or electric vehicle.

It is designed for marines, small ports and shipyards, as well as for dry marines, facing the everlasting problem of suctioning liquid waste from vessels.

MMVP mobile marine vacuum pumps in the marina

Operating mode:

The mode of operation is very simple, liquid waste is sucked directly to MMVP tank by underpressure (vacuum).
Discharging of liquid waste from the MMVP tank is performed on basis of the pressure intentionally accumulated for discharging liquid waste to sewage or into the cesspool.
Such the system of suctioning and discharging liquid waste provides that both operations are performed without the transit of the liquid waste through the pump, but directly to the tank, i.e. from the tank.
This surely provides an advantage for the reliability and durability of the pump. Therefore, there are no maintenance expenses.

The trailer of the MMVP unit is equipped with a mechanical braking system on front wheels for safety reasons, which provides stopping of the unit at any moment, especially when discharging at marine docks, i.e. during discharging. Braking is performed by lifting the movable beam.

The beam also has the possibility of vertical and horizontal moving, which is very important in case of towing over rough terrain.

Monitoring of the operational phase is provided by:

  • MMVP unit is equipped with an external manometer for monitoring of underpressure in the tank,
  • glass window for visual control of the level of liquid waste,
  • a safety valve that prevents overfilling.
