Prominent Metering Pumps

Concept PLUS Series (red)

The ProMinent® Concept Plus series covers a capacity range of 0.16 to 3.17 GPH (0.6 to 13.5 LPH) at pressures up to 232 psi (16 bar). Its compact construction and features make it ideal for use in flow proportional or on/off control applications. The Concept Plus mounts easily onto a tank or wall bracket. Adjustment of the pump capacity is via the stroke length in the range of 10-100% or can be set at 1 of the 4 stroke frequency settings. This gives an aojustment ratio of 40:1.

Features & Benefits

  • NSF 61/50 approvals
  • Low cost opens up opportunities in the most basic applications
  • PVDF wetted ends eliminate compatibility concerns
  • Integral bleed valve prevents "loss of prime"
  • Lowest maintenance costs in its class
  • External control via dry contact pulse (1:1)
  • Wetted end materials: PP, Acrylic/PVC or PVDF

Series AA, B & C Chemical Metering Pumps (shown)

Series AA, B & C Chemical Metering Pumps have been an industry standard for over 20 years. The familiar yellow and black pumps have a rugged, totally enclosed, chemically resistant housing for protection in the harshest environments. Encapsulated electronics and a rigid housing and stroke bracket ensure years of precise, repeatable performance. Several control options are available for all applications and budgets:

Type "9" control is designed for easy integration into chemical feed systems. The stroke rate may be controlled manually or by an external signal generated by a flowmeter, controller, transmitter, PLC or other device. Divide or multiply a digital (pulse) input or program a response to a milliamp (4-20, 0-20, 20-4, 20-0) input. Remote on/off and low level inputs are standard. The clear liquid crystal display provides the user with operational status. The unique 5-level power control reduces system shock and extends the life of the pump. The optional Digi-Pulse Flow Monitor verifies chemical flow and provides an alarm output.

Type "7" control is designed for more economical systems. The stroke rate may be controlled manually or by a digital input. The optional Micropace Control Modules enable the user to divide or multiply a digital input or respond directly and proportionally to a 4 - 20 milliamp input. A low level input is standard.

Type "1" control is designed for accurate chemical feed where manual or on/off control is all that is required. Dual manual control of stroke speed and stroke length are provided.
