Suction anchor pumps mounted on ROVs are the cost effective method
of installing deepwater suction anchor piles in soft sediment seabed
materials. The suction anchor pile is now a regular feature in modern
deep underwater engineering projects.
AT30 ROV Suction Anchor Pumps
Following repeated requests for high flow
at low suction differential pressures we are now completing the
final stages of the AT30 Turbine Suction Anchor Pump development.
Designed for suction pressure differentials of less than 1.5 bar
this pump has a novel and extremely simple flow reversal system
when compared with previous designs of ROV suction anchor pump systems.
The operating characteristics of the pump have been optimised to
maximise safety when installing low pressure anchors. Operating
data, installation specifications and pictures of this pump will
shortly be available on demand for interested end users.
The Heavy Duty ROV Suction Anchor Pump
The AZ20 is the advanced heavy duty ROV suction anchor pump designed
and built by AMITS. It provides twice the performance of the AZ10
in a very similar package size. The performance enhancements are
the result of new porting, a new impeller design and a larger motor.
Despite being a more powerful pump the unit offers finer progressive
control at the low suction pressures demanded by installations in
soft unstable soil conditions. This pump has a high hydraulic power
demand and is optimised for the most powerful work class ROVs.
The AZ20 suction anchor pump is now in full series production.
Some of the first production batch are shown alongside in the workshop
The AZ20 has been thoroughly tested in real harbour seawater conditions
on the south coast in a programme that spanned across two months.
The AZ20 is distributed directly by AMITS in Europe and the Eastern
Hemisphere. In the US and Western Hemisphere the Pump is manufactured
and distributed by Oceanworks International in Houston.
The AZ20 series suction anchor pump is built and distributed in
Europe directly by AMITS and in the US by Oceanworks. The AZ20 is
optimised for the high power deep water ROVs.

The AZ10 Anchor Zip suction anchor pump shown further below provides
an effective suction anchor installation capability and has a hydraulic
power requirement compatible with the majority of older work class
The AZ10 combines the pump and a directional valve in a compact
In addition to the AZ10 there is a smaller design , the AZ05 with
an integral bidirectional valve which has been optimised for use
from the larger inspection class of ROVs with hydraulic power packs.
The bidirectional AZ05 is shown installed on a Perry Tritech Viper
