Submersible
Turbine pumps
The Oase STP series 6 " and 8 " Submersible
Turbine Pumps are designed specifically for architectural,
municipal, and commercial fountain applications. Seven
series of 6" pumps with flow rates up to 550 GPM,
and two series of 8" pumps with flow rates up to
1000 GPM are offered. Standard configurations include
all single and two stage pumps, with a maximum of eight
stages offered for extreme pressure requirements. The
Oase STP series pumps meet the rigid technical standards
and specifications used in the design of architectural,
industrial, commercial, and municipal applications.

Oase STP pumps can be used
in installations fed with city water supplies, or reclaimed
water supplies. Unlike submersible sump pumps, the Oase
STP pump is designed for the continuous use duty of an
architectural water feature. All STP pumps are cast iron
construction with brass or stainless steel impellers,
with brass or stainless steel mounts, and a stainless
steel suction screen and cooling shroud. Motors are stainless
steel water cooled types, with no internal oil to leak
out. STP pumps can operate in as little as 18" of
water depth. Designing your fountain using Oase submersible
equipment will save installed cost, as there is no requirement
for a buried vault or any suction plumbing. Typically,
a 24" deep sump is incorporated into the fountain
design (covered with a fiberglass grate) and a direct-burial
external filter used. This can result in an installed
cost savings of 20% or more over a buried vault system!
Oase Pumps & Fountains has a staff of experts trained
and experienced in practical and technical engineering
problems and are capable of designing and building the
finest in turbine pump equipment. Our exacting standards
of highest-quality materials, engineering, inspection,
and testing are your assurance that the Oase STP pump
will deliver dependable performance for your application.
Technical Description:
- Standard sizes from 1Hp to 30Hp, single or dual
stage configurations. Larger Horsepower and three
or more stages are available as specials
- Available in single or three phase power, 60Hz standard,
50Hz available (for 50Hz operation, derate the pump
curves approximately 20%). Single phase pumps 2Hp
and larger require an external starter capacitor box
- Cord length is 10 ' standard. Longer cord lengths
are available on request
- Discharge is axial female NPT threads. For ease
of installation and best serviceability, it 's recommended
that a flanged fitting and wafer type butterfly valve
be used on the outlet
- Discharge, Intermediate Bowls and Motor Brackets:Heavy
duty class 30 cast iron for maximum efficiency and
abrasion resistance
- Reliable long life bronze bearing in every stage.
- Impeller:Balanced lead free silicone bronze, enclosed
impellers designed for maximum efficiencies with a
wide range of hydraulic coverage and corrosion resistance
- The NFPA NEC (National Electrical Code)Article 680
(Fountains) limits submersible pumps to 300 volt or
less operation and requires a Ground Fault Circuit
Interrupter (GFCI or GFI) listed for personnel protection
be installed. For this reason, we don't offer any
submersible pump for distribution in the USA with
an input power higher than 240 volts. Provide proper
GFCI protection on installation
- 10 ",12 " & 14 " Turbine Submersibles
are also available, utilizing a vertical turbine bowl
and fabricated brackets. Contact our application engineers
