Description

The Blackmer LGL Series 1.25 inch to 1.5 inch sliding vane pumps are ductile iron, motor speed propane pumps built for motor fueling, multiple station cylinder filling and small transfer duty. Every model is listed by Underwriters Laboratories for LP-Gas and anhydrous ammonia service, and every model carries a cavitation suppression liner that cuts the noise, vibration and wear normally caused by entrained vapor.

All six models share the same wet end architecture: an eight vane Duravane rotor, an integral relief valve, a Blackmer single mechanical seal, Buna-N elastomers, external ball bearings isolated from the pumpage, and NPT tapped ports. The replaceable liner, discs and vanes let the pumping chamber be rebuilt to like new condition without replacing the pump.

Models carrying an R use a reduced flow liner. Models carrying an F are supplied with an integral bracket and a flexible shaft coupling, ready to accept a NEMA C-face or IEC flanged face motor. Models without an F are foot mounted and are driven through a separate coupling or an integrated unit assembly.

Rotation and Motor Adaptor

Rotation is selected above and is viewed from the driven end of the pump. Right hand (CW) is the standard build and left hand (CCW) is available at no cost. Choose the direction that matches your driver.

The Motor Adaptor selection depends on how the pump is mounted. The three foot mounted models, LGRL1.25, LGL1.25 and LGL1.5, are supplied foot mounted less coupling, which is their only adaptor selection. The three flanged models, LGRLF1.25A, LGLF1.25A and LGLF1.5A, are supplied with a motor adaptor and coupling matched to your motor frame, and offer six selections:

Motor Adaptor Applies to
Foot mounted, less coupling LGRL1.25, LGL1.25, LGL1.5
Footless adaptor and coupling, 56C motors LGRLF1.25A, LGLF1.25A, LGLF1.5A
Footless adaptor and coupling, 143-145TC and 182-184C motors LGRLF1.25A, LGLF1.25A, LGLF1.5A
Footless adaptor and coupling, 182-184TC and 213-215C motors LGRLF1.25A, LGLF1.25A, LGLF1.5A
Footed adaptor and coupling, 56C motors LGRLF1.25A, LGLF1.25A, LGLF1.5A
Footed adaptor and coupling, 143-145TC and 182-184C motors LGRLF1.25A, LGLF1.25A, LGLF1.5A
Footless adaptor and coupling, IEC 100/112 B14A face mount motors LGRLF1.25A, LGLF1.25A, LGLF1.5A

Footless adaptors require a motor with feet. Footed adaptors are suggested for motors without feet. All motor adaptor selections are supplied at no additional cost.

Integrated Unit Assemblies

Blackmer Integrated Unit Assemblies are a pre engineered drop in package that pairs the pump with a motor, baseplate, coupling and coupling guards, with no field alignment required. Direct mount assemblies are offered for the foot mounted models across NEMA 56 through 215T frames, and for the flanged models across 56C through 184TC frames. Unit assemblies are priced separately from the pump and motor. Call to Order (262) 646-4500 to have one configured.

Ordering

Select your model, rotation and motor adaptor above to see pricing for that exact build. Not every motor adaptor is offered on every model, so if a selection shows Call to Order it means that combination is not built by Blackmer for the model you picked. We are an authorized Blackmer distributor and can help you size a pump, match it to a driver, quote an integrated unit assembly, or identify the right kit for a pump already in service. Call (262) 646-4500.

Frequently Asked Questions

What industries or applications are best suited for the LGL Series 1.25 inch to 1.5 inch Ductile Iron Pumps?
The LGL Series 1.25 inch to 1.5 inch Ductile Iron Pumps are ideal for motor fueling, multiple station cylinder filling, and small transfer duties. They are built for LP-Gas and anhydrous ammonia service, making them suitable for industries such as energy, agriculture, and industrial gas distribution.
How does the cavitation suppression liner benefit the operation of the Blackmer LGL pump series?
The cavitation suppression liner reduces noise, vibration, and wear caused by entrained vapor during operation, helping to extend the pump's service life and maintain more consistent performance.
What are the key differences between foot-mounted and flange-mounted models of the LGL Series 1.25 to 1.5 inch Ductile Iron Pumps?
Foot-mounted models are designed to be mounted directly on a base or surface and are driven through a separate coupling or integrated unit, while flange-mounted models include an integral bracket and are ready to accept a motor with a flanged face, offering easier installation and alignment options.
