B&G SERIES 80 - AN EFFISIENT RUGGED CLOSE COUPLED PUMP
DESIGNED FOR VERTICAL AND HORIZONTAL IN-LINE MOUNTING |
| |
| The Series 80 is an efficient, heavy-duty, close coupled pump designed for horizontal and vertical in-line
mounting. Available in sizes 11/2" through 8". 1/4 to
50 HP at 1750 RPM and 5 to 60 HP at 3500 RPM. Available in bronze fitted and all cast iron construction. Flows to 2500 GPM, heads to 380 ft. Available in 175#, 250# and 300# working pressure designs |
| |
| MOTOR BRACKET |
| Precisely machined rigid cast iron motor bracket ensures positive concentric alignment between
motor and pump components. This helps promote maintenance free operation and contributes to pump longevity |
| |
| VOLUTE |
| Standard construction is for 175 psi working pressure, with flanges drilled to mate with 125# ANSI companion flanges. 250 psi and 300 psi working pressure with 250# flange drilling is optionally available |
| |
| MOTORS |
| Standard NEMA JM and JP vertical solid shaft motors in dripproof enclosures are utilized on B&G Series 80 pumps. High efficiency motors, as well as TEFC and explosion proof enclosures are available options. Motor may be rotated on its bracket at 90° intervals to allow convenient positioning of the junction box |
| |
|
| INTERNALLY FLUSHED MECHANICAL SEAL |
| The B&G built-in mechanical seal with anti-vortex baffles in the seal chamber provide five times the flow around the seal face versus an externally flushed seal. Costly and inefficient external flush lines are not needed. |
| |
| CONVENIENT TO INSTALL |
| In-line mounting eliminates the need for special pads or foundations in most cases. Standard piping supports on both sides of pump are required at all the times. The support ring located on the underside of pump volute is designed to provide ground support when necessary. |
| |
| HORIZONTAL MOUNTING |
| Pump may be mounted horizontally in vertical piping if desired. |
| |
| CONVENNIENT TO SERVICE |
| Back pullout design allows servicing without disturbing the piping. Repairs can be made quickly and easily. Thus down-time is kept to a minimum. |
| |
| IMPELLER BALANCED TO ANSI/HI GRADE G6.3 |
| Quiet, vibration free operation results from this efficient balancing method. Factory selected diameters ensure that required performance will be attained. |

| TYPICAL SPECIFICATION |
| |
|
|
|
| Furnished and installed with capacities as shown on plans. Pumps shall be in-line type, close-coupled single stage design, for installation in vertical or horizontal position, and capable of being serviced without disturbing piping connections. |
| |
| Pump casing shall be of Class 30 cast iron. The impeller shall be of cast bronze, closed type, balanced to ANSI/HI Grade G6.3, keyed to the shaft and secured by locking capscrew. |
| |
| The liquid cavity shall be sealed off at the motor shaft by an internally-flushed mechanical seal with ceramic seal seat and carbon seal ring, suitable for continuous operation at 225°F. |
| |
| A bronze shaft sleeve shall completely cover the wetted area under the seal. |
| |
| Pumps shall be rated for minimum of 175 psi working pressure (optional 250 psi and 300 psi working pressure). The pump case shall have gauge tappings at the suction and discharge nozzles and will include drain ports. |
| |
| Motor shall meet NEMA specifications and shall be the size, voltage and enclosure called for on the plans. It shall have heavy-duty, grease lubricated ball bearings, completely adequate for the maximum load for which the pump is designed. |
| |
| Each pump shall be factory tested per Hydraulic Institute standards. It shall then be thoroughly cleaned and painted with at least one coat of high-grade machinery enamel prior to shipment. |
| |
| Pumps shall be Series 80 as manufactured by ITT Bell & Gossett or equal. |
