Battery pump for flexible portability

Friday, November 23rd, 2018 von admin

High pressure hydraulic tools specialist, Enerpac, announces the ZC-Series cordless hydraulic pump combining the performance of an electric pump with the convenience and portability of a battery pump. The ZC-Series is ideal for jobs that require a combination of portability, speed and safety.

These cordless pumps work well for remote locations without access to power and indoors where trip hazards, ergonomics or size is a concern. The ZC-Series pumps are suited for use in industrial applications such as foundation repair, rail maintenance and concrete post-tensioning. Since this cordless solution is quiet, it’s also ideal for applications where noise and emissions from gas powered equipment are a concern.

Three-screw pump for high-pressure machine tool coolant service

Thursday, August 16th, 2018 von admin

Intended for use in metalworking applications, transfer lines, and grinding and deep drilling machines, Emtec-C pump delivers coolant at a high flowrate, allowing machines to run at peak levels without compromising tool life.

“We’ve improved Emtec-C to achieve maximum three-screw pump efficiency with a lighter weight and fewer components,” said Kapil Rai, Circor Vice President, Industrial Pumps, EMEA, India & Asia. “It also features several difference-making innovations.”

Bubble-free filling of oil dampers

Monday, November 27th, 2017 von admin

Filling of oil dampers in low-volume and pilot production is mostly manual work. There is a lot of potential for improvement by a compact, flexible dosing system which includes a micro metering pump. This self-priming micro annular gear pump can work without an application of compressed air to the reservoir.

On the one hand, this saves the cost of compressed air including the necessary devices and, on the other hand, avoids the introduction of compressed air into the silicone or hydraulic oil. The medium can be filled bubble-free, gently and without loss of quality.

HNPM: New modular micro annular gear pump

Friday, September 1st, 2017 von admin

This micro annular gear pump allows accurate displacement volumes from 100 μl to 1,000 ml in a metering time of 200 milliseconds up to one minute. It also covers a flow rate range of 0.2 to 1,152 ml/min. Different materials are available for wetted parts. The pump operates with high dynamics, low pulsation and excellent precision in delivery as well as high repeatability in metering. The pump is suitable for low to high viscosity liquids and a differential pressure of up to 10 bar. Other pump series are available for applications with different requirements.

The pump is supplied with lateral fluid connections and a pump bearing bracket or with a so-called M4 version. The manifold version M4 has frontal fluid connections and allows assembly to a manifold which is supplied by HNPM or provided by the customer.
