Page 1 - SPMV Series - High Capacity AC Motor/ Pump Units

High Capacity AC Motor/Pump Units
Designed for high capacity applications where 430-1730 gph
are required. Quiet running, gear type pumps are available in
four sizes and incorporate hardened integral shafts, journals
and gears, special anti friction bearings, Buna N seals, and
cast iron gear plates. Standard motors ranging from 1/2 hp to
hp (373 W to 5.6 kw) are 1725 rpm NEMA “C” face, 115
volt single-phase or 230 volt three-phase, 60 cycle type with
TEFC enclosures through 2 hp (1490 W) and OPDP enclo-
sures over 2 hp (1490 W).
Webster AC motor/pump high capacity fuel oil supply units
are designed to be used with fuel oils including JP4 whose
viscosities do not exceed 6,000 S.U.S. and with a suction
less than 10” of mercury or an inlet pressure not to exceed
psi continuously (capable of intermittent duty at 10,000
S.U.S., 20” of mercury and 50 psi inlet). The unit is designed
to operate in -20°F to +200°F conditions. The motor is preci-
sion aligned and coupled to the pump with a machined
adapter and flexible couplings.
Pump/Motor Units
Available in flow rates from 430 GPH through 1730 GPH.
Systems can be designed for single phase 115/208/230V, 60
or 50CY, or three phase 208/230/460V, 60 or 50CY, applica-
tions. The SPM duplex models consist of two pump and
motor assemblies with a pre-pipded common discharge
manifold. One pump operates continuously, with the second
providing backup services if the main pump fails. Either auto-
matic (SPM-DA models) or manual (SPM-DM models) con-
trols are available. The duplex automatic series are designed
specifically for buildings where a constant supply of oil must
be assured...hospitals, apartment buildings, schools and
other commercial or industrial buildings. The duplex pump
set has a second pump for standby or auxiliary service.
Furnished with automatic or manual standby controls, the
duplex automatic is equipped with a pressure sensing device
which detects loss of pressure of primary pump. If stanby
pump is brought into service, an alarm sounds which indi-
cates malfunction in primary pump. The electric control cir-
cuit on the duplex automatic pump set is equipped with a
lead-lag switch to permit manual alternation of pump to pro-
vide even pump wear. The manually operated duplex pump
sets offer the same protection as the automatic except the
standby pump must be turned on manually which requires
that maintenance personnel always be available. Available
with either SPM or SPMV pump/motor units.
