Mechanical Sealed Pumps - horizontal centrifugal

The impeller is directly connected to the driven shaft from the motor.  The shaft of the pump exits the rear of the pump and are sealed with a mechanical seal.  The seals is two highly polished surfaces - one rotating with the impeller - the other is stationary with the pump.  They are lubricated by the product being pumped or by a external water flush.

Mechanical sealed pumps have advantages

• the motor torque is direct to the impeller
• the shaft is solidly supported to allow for clearances required for abrasive liquids
• the ability to deal with a high concentration of solids in solution
• a wide variety of seal combinations to deal with most all applications
• mechanical seals offers the pump designer greater flexibility to design special purpose pumps

Thermoplastic Pumps - for corrosive and high purity chemical solutions
Metallic Pumps below

HV Series - 25 to 125 GPM

CPVC  horizontal centrifugal pumps designed for corrosive applications.  1/2 HP to 2 HP
The "true volute" design offer high efficiency and hydraulic balance for the impeller.  Offers no metals in contact with solution.   Choice of single or double flushed mechanical seals.  Details

HOM Series - 20 to 120 GPM

Polypropylene horizontal centrifugal pumps are designed for semi-corrosive applications.
1/2 HP to 2 HP. 
The volute design offer high efficiency and hydraulic balance for the impeller.  Pressure to 75 feet.  Mechanical seal is carbon vs. ceramic with EPDM or Viton® elastomer.  The seal configuration is inside mounted. HOM Series pump are mounted on a 56JP motor -- this would allow motor being furnished by local sources.  All units are supplied with a TEFC motor as standard. Designed and priced for the OEM market.   Details

HN Series - 70 to 180 GPM

CPVC horizontal centrifugal pumps are designed for corrosive applications.
3 HP to 7 1/2 HP. 
The volute design offer high efficiency and hydraulic balance for the impeller.  Pressure to 146 feet.  Mechanical seal is carbon vs. ceramic (optional carbon vs.silicon carbide) with EPDM or Viton® elastomer.  The seal configuration can be outside mounted (standard) or double water flushed (requires 3 - 5 GPH water).  HN Series pump are mounted on a 184JP motor -- this would allow motor being furnished by local sources.  All units are supplied with a TEFC motor as standard.       Details

GP Series - 30 to 240 GPM

Polypropylene or PVDF construction pumps provide reliable service for high volume transfer or re-circulation of corrosive liquids. The thermoplastic resins use a fill material of glass or carbon for additional strength and wear resistance. Mechanical seal options allow for difficult solution applications – these types of options are not normally available with thermoplastic pumps. The pump can be supplied direct mounted to a TEFC motor – Motor options included "Chem Duty" and "Explosion Proof"  Details

• Pressure to 120 Feet
• Close coupled motors ¾ HP to 10 HP
• Pedestal mounted option
• Mechanical Seal option

HD Series - Multi Stage for High Pressure

CPVC multi-stage horizontal diffuser pump is designed for high-pressure applications where a metallic pump is unacceptable. Create pressures comparable to pumps with impellers 2 or 3 times their diameter size. with less disk friction loss. 316SS or optional titanium shaft allowing for temperatures to 200 F. Single mechanical seal is carbon/ceramic.  316SS or titanium shaft.Ideal flow rate for these pumps is 7 to 75 Gallons Per Minute. Pressures to 145 feet  Details

Metallic Pumps

M Series - 10 to 750 GPM

Cast Iron Centrifugal pump for industrial and commercial applications
1/3 - 25 HP
Pumps are mechanical sealed close coupled or frame mounted.  Optional - Bronze fitted or All Bronze in most models.  3500 and 1750 RPM models - pressure to 280 feet   Details 

Pumps are constructed of stamped and formed 316 stainless steel materials.  Type 21 mechanical seals are use in the horizontal pumps with Teflon bushing for all vertical pumps.  All pumps are rated to a minimum of 100 PSI and suitable for temperatures to 300 F.    Details

LaBour / Taber -- northern Illinois and NW Indiana only

ANSI B73.1 Standard - Single and Triple Volute designs

Self-Priming centrifugal process pumps

Vertical process pumps to 36 feet in length  Details

G & L div. of Gould Pumps - 25 to 1050 GPM  316 SS centrifugal

Pumps are constructed of stamped and formed 316 stainless steel materials.  Horizontal and Vertical pumps for general water transfer to pressurized water systems. Details
