Wilden Saniflo Hygienic Series with Pure-Fuse Diaphragm vs. Murzan

Murzan publishes minimal data regarding the performance of their pumps. Because of this, Wilden conducted a head-to-head test in its test lab, which is setup in accordance to the Hydraulic Institute’s testing standards. The test pitted Murzan’s 76 mm (3”) pump against the Wilden 76 mm (3”) Pro-Flo®SHIFT Saniflo Hygienic Series (HS) Pump with Pure-Fuse Diaphragms

Murzan and Wilden were tested under identical application conditions. At all data points – from an air inlet of (40 psig with 0 psig discharge) to an air inlet of (120 psig with 90 psig discharge) – the Wilden HS pump outperforms Murzan’s pump both in product yield and air consumption.

  • Max Flow – 52 GPM more than Murzan
  • Product Yield – 34% more

Additionally, the unique design of Wilden Saniflo HS pumps incorporates a free-draining flow path that optimizes performance and enables clean-in-place (CIP) capability while allowing the pump to meet all 3A requirements. It is by design that the HS pump does not have any catch areas for product to remain inside the pump. Catch areas can create potential bacteria growth, contaminating the product.

Wilden AODD Pumps Competitive Advantage

According to Wilden Pump, “In AODD pump operations, energy use is directly related to the rate of consumption of air used to drive each stroke of the pump during the pumping cycle. With today’s high energy costs, the initial purchase and installation of a new pumping system is only a small part of the total cost of ownership and operation during the pump’s life cycle. Routine costs of energy and maintenance remain the primary cost drivers in the total cost of ownership.

Much like cars, pumps can be rated according to efficiency. The goal is to utilize the least amount of air to pump the greatest amount of product. The ultimate objective is to reduce the rate of air consumption in relation to the product flow rate while also minimizing the overall amount of air that is not producing product yield (wasted energy) during the pumping cycle.

If attained, this combination will directly impact an operation’s bottom line — the profitability being determined by something as simple as the volume of air being consumed and the energy required to compress it. In addition to wasted energy, air overfilling stretches the diaphragm unnecessarily. This stretching produces excessive diaphragm wear and tear resulting in more frequent replacement and downtime, while also increasing operating costs.
