LMI UD001-238NU Discontinued – Replacement Metering Pump Options
The LMI UD001-238NU UniDose Metering Pump has been discontinued and is no longer available for purchase. However, Water Treatment Supply offers alternative chemical metering pumps for industrial water treatment, chlorine injection, and chemical dosing applications.
The original LMI UniDose pump provides an adjustable flow rate of 1–24 GPD, a maximum pressure of 80 PSI, and 115V AC operation. Therefore, selecting a suitable replacement requires comparing these specifications with your system’s operating requirements.
Recommended Alternative: Pulsafeeder X024-XA-AAAFF04
The Pulsafeeder X024-XA-AAAFF04 100 Series Metering Pump is a potential alternative to the discontinued LMI UD001-238NU.
This model offers a maximum flow rate of 24 GPD, a pressure rating of 100 PSI, and 115 VAC operation with manual control.
As a result, it matches the original LMI pump’s listed maximum dosing capacity and voltage. In addition, its higher listed pressure rating may suit certain applications that require additional pressure capacity.
However, buyers must verify the actual operating flow, chemical compatibility, wetted materials, and installation connections before selecting this pump.

Alternative Option: Stenner 85MHP17
The Stenner 85MHP17 Adjustable Dosing Pump offers another option for chemical injection and water treatment applications.
This model provides an adjustable flow rate of 0.8–17 GPD, a maximum pressure rating of 100 PSI, and 115V operation.
Therefore, the Stenner pump may suit systems that require no more than 17 GPD. However, its maximum dosing capacity is lower than the original LMI pump’s 24 GPD rating.
In addition, its peristaltic pumping technology differs from the original LMI design. Consequently, buyers should review tubing, chemical compatibility, and installation requirements before making a selection.
