New Product: Blackmer NPH4F 180 Deg. Pump
Semler Industries is pleased to announce the launch of the new Blackmer NPH4F Sliding Vane Pump. While it offers the same performance of the standard NP4F pump, the NPH4F features 180 degree ports as opposed to the standard 90 degree ports.
Like the standard NP4F, NPH4F features ductile iron construction with an internal relief valve that protects against excessive pressures, ensuring performance and reliability even under the most severe service conditions.
Additional features and benefits of the NPH4F include: optional cartridge mechanical seal, lip seal, or triple-lip cartridge seal over the standard shaft packing; 4” weld, 4” ANSI 150# RF compatible, or 4” NPT
flanges. Options for jacketed heads are also available. NPH4F pumps are available with differential pressures up to 200 psi (13.8 bar) and maximum pump speeds of 500 rpm
