Vacuum Pumps

 

EVC Vacuum Pumps

Economical vacuum and condensate units with independent air and water pumps have a multi-jet design proven to be an effective and reliable means of removing air and lifting hot condensate in the return system. The units come with standard heavy-gauge, 1D 4" thick black steel receivers for years of reliable service. Receivers are divided into two compartments. One side is used for collecting and blending the hot condensate with the cooler make-up water. The other side is the vacuum chamber. Standard units are designed for applications with system capacities ranging up from 10,500 square feet (975 sq meters) EDR. Air pumps range up from 5.8 cubic feet per minute (2.7 liters per second) at 5-1D 2" (140 mm) HG at 160°F (71°C). Units are completely packaged, including electrical controls.

Units are available in simplex, duplex, or semi-duplex configuration with 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. The pumps are bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F. Seals for higher temperatures and special faces are available.

 

LRV Vacuum Pumps

Low-return vacuum heating units have a combination air/water pump that performs both the condensate- and vacuum-pumping functions. The pumps use a multi-jet design proven to be a reliable and effective means of removing air and lifting hot condensate in the return system. Standard cast iron receivers have a 20-year warranty against corrosion failure. These units are designed for applications with low returns and system capacities ranging up from 2,500 square feet (232 sq meters) EDR. Air pumps range up from 3 cubic feet per minute (1.4 liters/second) at 5-1D 2" (140 mm) HG at 160°F (71°C). Units are completely packaged, including electrical controls.

These pumps are available in either simplex or duplex configuration with 1750-RPM or 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. Pumps are also bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F (121°C). Seals for higher temperatures and special faces are available.

 

LRV-S Vacuum Pumps

Low-return vacuum heating units have a combination air/water pump that performs both the condensate- and vacuum-pumping functions. These pumps use a multi-jet design proven to be a reliable and effective means of removing air and lifting hot condensate in the return system. The standard steel receivers provide years of reliable service. Standard units are designed for applications with low returns and system capacities ranging up from 2,500 square feet (232 sq meters) EDR. Air pumps range up from 3 cubic feet per minute (1.4 liters/second) at 5-1D 2" (140 mm) HG at 160°F (71°C). Units are completely packaged, including electrical controls.

These pumps are available in either simplex or duplex configuration with either 1750-RPM or 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. Pumps are bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F (121°C). Seals for higher temperatures and special faces are available.

 

BVC/BVMC Vacuum Pumps

Big vacuum and condensate units have independent air and water pumps, and they use a multi-jet design proven effective and reliable for removing air and lifting hot condensate in the return system. The standard cast iron receivers come with a 20-year warranty against corrosion failure. The vacuum tank (or hurling chamber) is heavy-gauge, black steel or cast iron, depending upon sizing. Standard units are designed for applications with system capacities ranging up from 1,000 square feet (93 sq meters) EDR. Air pumps range up from 5.8 cubic feet per minute (2.7 liters per second) at 5-1D 2" (140 mm) HG at 160°F (71°C). Units are completely packaged, including electrical controls.

These pumps are available in either simplex or duplex configuration with 1750- RPM or 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. The pumps are bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F (121°C). Seals for higher temperatures and special faces are available. Air and water pumps can be sized separately for customized applications.

Type BVMC is the boiler-feed version of BVC pumps. An electrical solenoid make-up water valve with float-switch control is standard. A low-water cut-off switch is furnished to protect pumps should the make-up water assembly fail. Numerous options are available.

 

SHVC/SHVM Vacuum Pumps

Steel horizontal vacuum and condensate units have independent air and water pumps, and they use a multi-jet design proven effective and reliable for removing air and lifting hot condensate in the return system. Standard heavy-gauge black steel receivers from 3/16" to 3/8" thick provide years of reliable service. Receivers are divided into two compartments: One side is used for collecting hot condensate, and the other side is the vacuum chamber. Standard units are designed for applications with system capacities ranging up from 1,000 square feet (93 sq meters) EDR. Air pumps range up from 6 cubic feet per minute (2.8 liters per second) at 51D 2" (140 mm) HG at 160Ú°F (71Ú°C). Units are completely packaged, including electrical controls.

These pumps are available in simplex or duplex configuration with 1750-RPM or 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. Pumps are bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250Ú°F (121Ú°C). Seals for higher temperatures and special faces are available. Air and water pumps can be sized separately for custom applications.

Type SHVM is the boiler-feed version of the SHVC. An electrical solenoid make-up water valve with float switch control is standard. A low-water cut-off switch is furnished to protect pumps should the make-up water assembly fail. Numerous options are available.

 

BV Vacuum Pumps

BV pumps are big vacuum-producing units for clinical (hospitals and laboratories) and industrial processes. Mufflers or silencers are not required, because they are designed to be quieter than other types of vacuum pumps.

These pumps use a multi-jet design proven effective and reliable for removing air and for lifting hot condensate in the return system. The vacuum tank (or hurling chamber) is heavy-gauge black steel or cast iron, depending upon sizing. Standard units are designed for applications with system capacities ranging up from 1,000 square feet (93 sq meters) EDR. Air pumps range up from 5.8 cubic feet per minute (2.7 liters per second) at 5-1D 2" (140 mm) HG at 160°F (71Ú°C). Units are completely packaged, including electrical controls.

Units are available in simplex or duplex configuration with 1750-RPM or 3500-RPM single- or three-phase motors. Pumps are flange mounted to the receiver and equipped with industry-standard motors. Pumps are bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F (121Ú°C). Seals for higher temperatures and special faces are available.
