M34DK-3
to meet the needs of today's fuel-efficient, down-sized burners, Webster's
popular M34DK-3 fuel units provide fast fuel cutoff, and improved priming
performance on one pipe installations. In addition, the M34DK-3 operates
with a substantially reduced inlet flow on two pipe installations,
resulting in significantly lower line noise. Webster's M34DK-3 fuel units
are available in single stage, 3450 rpm models rated at 3 gph. Operating
pressure is factory set at 100 psi. The M34DK is able to maintain its 3
gallon fire size throughout the 100 to 150 psi pressure range.UL listed. |

Single and two stage models with 1725 and 3450
rpm operation feature compact design and field-proven reliability. These
units, rated @ 3 to 25 gph (11 to 57 1/hr.) @ 100 psi (6.9 bar), can be
used on one or two pipe installations. Double lip type seals assure low
starting torque and provide positive protection from leaks. M series fuel
units utilize the unique Webster rotary filter to minimize maintenance. UL
Listed. |

Webster's service saver R series fuel units are
available as both single and two stage units with capacities to 75 gph (284
1/hr.), Satisfying virtually every replacement need. The R series
incorporates Webster unique rotary filter, reducing the need for periodic
cleaning. To assure positive protection form leaks, double lip seals are
used, providing lower friction than face type seals. UL listed. |

Webster V series fuel units are designed to meet
the high delivery requirements of commercial and industrial systems, with a
minimum of mechanical and hydraulic noise. Available in both single and two
stage models. Single stage units provide a firing rate up to 260 gph (980
1/hr) at up to 10' hg (254 mm) inlet vacuum. Two stage firing rates are as
high as 200 gph (760 1/hr) at up to 15' hg (381 mm) inlet vacuum.
Operational integral regulating valves are factory pre-set for 100 and 300
psi (6.9 and 20.7 bar) operation and can be easily adjusted in the field
for specific system requirements. UL listed. |

B series transfer pumps provide efficient
pumping of #1 to #6 oils, in capacities from 80 to 290 gallons per hour, at
pressures up to 500 psi (300 psi with #1 oil). B series pumps are available
in either right-hand or left-hand cofiguration. 18B, 37B, 47B series pumps
have ½” NPTF porting, and the 59B series pump has ¾” side inlet and side
outlet porting. UL listed. |

Webster 35223, 49116 and 35202 series pump
units combine an electric motor and fuel unit or transfer pump to provider
a broad range of pumping capabilities for transferring and supplying oil.
The 35223 series pump/motor unit consists of a Webster B series fuel oil
transfer pump motor with working pressures up to 200 psi. The 49116 series
pump/motor units consist of a Webster 1R00 series fuel transfer unit close
coupled to a 1/4 hp electric motor capable of up to 66 gph at 100 psi. The
35202 series pump/motor units consist of a Webster R series or V series
fuel unit close coupled to a motor. This series is available with 1/6, 1/4,
1/3 hp or 1/2 hp electric motors with a pumping capacity to 66 gph at 100
psi. |

Developed to supply fuel oil to one or more
overhead furnaces, day tanks, or for underground central distribution. Four
pump/motor sizes are available, with capacities of 15, 30, 65 and 135 gph
(57, 114, 245 and 510 1/hr). 1/6 hp, 1/4 hp and 1/3 hp (124W, 186W and
248W) motors are split phase available for either 115 or 230 volt
operation. 1/2 hp (373W) motors are capacitor start -induction run, totally
enclosed with dual 115/230 volt windings. The units are shipped completely
assembled and include gauge, vacuum breaker and check valve. All are 60
cycle, 1750 rpm, continuous duty. |

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 standby pump is brought
into service, an alarm sounds which indicates malfunction in primary pump.
It is equipped with a lead-lag switch to permit manual alternation of pump
to provide even pump wear. Available with either SPM or SPMV pump/motor
units. |

Ideal for use in oil supply systems which have
form 0 to 60 psi supply line pressures on the inlet side of the valve.
Requires a sustained vacuum on the outlet side of the valve for fuel to
flow to the burner pump. The OSV series provides automatic shut-off for the
oil supply in case the line between the device and the burner is broken.
Many state and local codes require such a device and also limit pressure on
burner pumps to a maximum of 3 psi. UL listed. |

The RV series are designed to provide system
pressure regulation for #1 through #6 fuel oil grades Rated pressure ranges
are for 0 to 500 psi. RV-2000 models also provide delivery cut-off for
capacities to 150 gph. RV-2100 regulates pressure only for capacities to
150 gph. RV-3000 regulates pressure for up to 600 gph. It can also be used
as a relief valve. |

Vacuum breaker valve incorporates Viton
"O" ring seat 3/8-18 NPTF ports. Can be used as a supply line
check valve. |

Designed for high capacity applications where
430 to 1730 gph are required. Efficient gear type pumps are available in
eight sizes and incorporate hardened integral shafts, journals and gears,
two pressure balanced war plates, special antifriction bearings, Viton
seals, and cast iron gear plates. Standard motors ranging form 1/2 hp to 15
hp (373W to 11.2kw) are 1725 rpm NEMA "C" face, 115 volt single
phase or 230 volt three phase, 60 cycle type with TEFC enclosures through 2
hp (1490W) and OPDP enclosures over 2 hp(1490w). |
